In this video, we're examining the recently released, scientific paper that examines the outcomes of CrossFit through a systematic Review and meta-analysis. The 2018 study was conducted by Claudino et al and is called "CrossFit Overview: Systematic Review and Meta-analysis". It was originally shared on our YouTube channel by one of our subscribers. You find the link in the study in the description; filed under "links". Unfortunately, what is most staggering (and at the same time sends chills down your spine) is the account where the authors dive deeper into the details of musculoskeletal injury risk. Scanning the paper for the word "injury" alone reveals 46 hits. We've compartmentalized the study into easy to understand bits and chunks of information and we hope you'll enjoy it! _ Time Stamp 00:00 Intro 01:00 Background & Objective Of The Study 04:50 Musculoskeletal injury Risk 10:32 Verdict Of The Study & Opinion On CrossFit 12:33 90 Days Of Kettlebells _ Links CrossFit Study: https://sportsmedicine-open.springeropen.com/articles/10.1186/s40798-018-0124-5 Website: https://www.lebestark.ch Kettlebell Kurse: http://academy.lebestark.ch Lebe Stark IG: http://instagram.com/lebestark Angie IG: http://instagram.com/angie_zoe_ziegler Gregory IG: http://instagram.com/gregory_dzemaili _ Music - Epidemic Sound - http://epidemicsound.com - StreamBeats - https://www.streambeats.com - StreamBeats License - http://bit.ly/streambeats-license) _ Hashtags #kettlebells #kettlebellstarkstyle

@smoggie28333 years ago In my opinion as we get older (and hopefully wiser...) the fitness aspect should take a back seat. Training for functionality, strength and mobility are more important for me (over 50 and train 6 times a week). As you rightly say Gregory - safety is paramount. I cringe when I see some of these people going all out like lunatics. I keep my mobility in good order so I can train with my KBs and that leads to functionality - namely good health - for me the fitness aspect is a by-product. Just my thoughts. ... 25

@chad11823 years ago I have several Cross fit friends and they have to take more time off from working out then me and I do kettlebells 5x week. Consistency is key, train smart so you can train more. 14

@swoosh28353 years ago My biggest issue with CrossFit is that Olympic lifts like the hang clean or clean and jerk should never ever be “AMRAP” or high repetition. Those lifts take years and years to coach in order to be done safely and to throw some 9-5 bro into that without proper coaching and doing 10 reps EMOM is a recipe for exactly what you shared in this video. ... 13

@KatsKettlebellDojo3 years ago I did competitive elite CrossFit for 5 years, all the way up to twice competing in international regional games. I also coached it. I never got injured, because I had amazing technique and wasn't stupid enough to compete during workouts. However, many people did get injured, because the format of the system is a recipe for injury and ego. And even regardless of how good your technique is, CrossFit takes a HUGE toll on the body. It took me 5 years after quitting to recover my hormonal balance. ... 3

@chrisdenning89053 years ago I did CrossFit for 4 years after switching from Muay Thai, I had trained with kettlebells on/off for a long time but it was actually using kettlebells in CrossFit that made me stop CrossFit, do a kettlebell certification and train primarily kettlebells. This study was intended to show the advantages/disadvantages of CrossFit, but I think it's been used unfairly to "show" that CrossFit is dangerous.. which it doesn't show at all, and given the high rate of bias (&many of the studies were questionnaire based for instance) it's not really worth the paper it's printed on (&the authors do note that there hasn't been enough quality studies to say either way). One of the studies used is from the NSCA which they admitted publishing fraudulent data. Also as you pointed out, the injury rate increases the more time you spend doing it, which is based on large increases in volume, so the athletes are under-recovered. I'm not a fan of a number of aspects of CrossFit.. AMRAP style workouts for example, especially for highly technical lifts. But I think EMOM's are brilliant. I also like what CrossFit has done to advance strength training in women and the idea of women being strong, vs just doing cardio and being too skinny. 💪 ... 7

@geeemm9093 years ago Another excellent video, Gregory. Over 20 years ago I started CrossFit training before it became big business and a sport. Back then it had a website with a daily WOD and a monthly news letter and you had a choice of wether or not you paid a subscription. I was bored with my method of trading and was looking for something new. It did give me some new ideas AND it introduced me to Kettlebells but I can honestly say I have never felt so permanently tired and had so many injuries. I stuck with it for about a year after which, thank goodness, I discovered Pavel Tsatsouline. I am now a keen follower of your videos and considering that English is not your first language you are more articulate than most English people and always speak with such great precision and clarity. ... 1

@wraymcclamma47073 years ago I've worked in special ops for over ten years. I started kettlebells with the Russians back in 2005 with Pavel, S Puzikas and Bud Jeffries. I started training Crossfit in the middle of my special ops career preparing for tactical competitions. With kettlebells, I was a machine. Unstoppable. Crossfit left me with an injured ACL, tendinitis, chronic fatigue and loss of mobility. I quit to begin recovery and I'll never do crossfit again. Kettlebells for life. Im 40 years old and function as well as I did in my early 30s ... 1

@8BitDeadlift3 years ago Can't call yourself functional training if it causes injuries to anyone who does it long term. Functional training is supposed to improve your quality of life, not cripple you. Here in Colorado, I've been to some boxes that have altered the crossfit model to have more periodization and progressive overload. So I think it's evolving but it still wants to cater to those who watch the games and want to chase that feeling of fatigue and exhaustion. Uncle Rhabdo will always have a place in crossfit unfortunately. ... 3

@vincentlee73593 years ago Why does crossfit get a bad rep? Simple: the coaches at most crossfit gyms don't know how to coach...they start a total beginner with olympic lifts and glossed over the technique using a body bar or a dowel, etc. 6

@henriquehansen3143 years ago I started my fitness journey years ago doing CrossFit, I had the luck to start with a good coach who made us spend a lot of time mastering the basics. In my point of view the biggest problem with Crossfit is that is the very opposite of the K.I.S.S idea and im more a minimalist guy. ... 4

@kyleblandon22503 years ago Any physical activity inherently has the chance for injury. Multiple peer-reviewed publications have indicated that with consistent training and moving correctly (i.e. the gym has taken the time to train you on the base movements and progress feom there) that the injury rate in crossfit is not significantly different in amount (per training hours) or severity than any other discipline as it relates to weightlifting (powerlifting, bodybuilding, oly, etc.). Running has a higher injury rate than any of them, why are we not focusing on dissuading people from running? ... 2

@alexanderarmando923 years ago Hi, I just started training kb again. I burned out on January. Meditating an listening to the part of the workout rest and the recovery interval. I would skip recovery time in the workout and train every day. Now I come to think about it couldn't be helped. Learned my lesson. Greetings from Mexico! ...

@danaromano6253 years ago These CrossFit fails make me 😭😢, I feel their pain. As a competitive and fanatical personality, it is hard to know when to stop and rest. Especially when you get older (I'm 52). I was so tempted to join CrossFit - but age and severe injury mitigated toward an intelligent and reasonable kettlebell program for me. I think my older, stronger, less injured, hopefully stroke-free, non-visually impaired self will thank me! ... 1

@jacklee7092 years ago Been doing CrossFit for 16 months but hadn't joined any WOD in a CF box until I spent a whole year to perfect most movements with my private trainer. I've seen so many new participants treating CF as just another intense cardio workout to get sweaty and burn fat while they're doing terrible squats and snatches. Well, it's good to keep yourself motivated through the intensity of WOD but long-term, you're gonna get injured for sure. So my humble advice, take some time to learn the basics before you get obsessed with those crazy WODs and treat it as a long-term learning process and you will eventually get what you want because exercise is not just about one WOD or a month, it's life-time. ...

He had to get spine surgery ...
@

@typeon3g4t1v33 years ago I do Crossfit 3-4x per week and KB training/weight training on 2-3x. Any time you train extremely intensely there is a chance of risk. As others have pointed out, coaching is the important part for novices and this is certainly uneven across gyms. I have not seen many injuries, however I can see how people can injure themselves. As you have pointed out, the key for more experienced people is not to get so invested in the work out that they sacrifice form. ...

@fitness_arena_mtl75133 years ago Drop the ego drop the weight. Good technique will have more results than heavy weights with bad technique. And if you injure yourself, you're losing out because of recovery time.
It's ok to push yourself every now and then, but I'd rather workout at 50-70 percent capacity but able to work out more frequently (hence more volume) than pushing limits all the time and losing out on workouts because of longer recovery time.
Work smart ... 2

@matsuwd-emethdaath40023 years ago This is insane self damage for people...hell I have done powerlifting. 400 to 600 lbs movements between squat / bench/ deadlifting and never had this much risk of danger nor was it known in powerlifting circles. Thats saying a lot in itself alone...smh
Same thing with BJJ classes I have done. No need for.the ego..." FIGHT TO THE DEATH" mentality. Enjoy what you are doing and make it last for you long term with quality of life benefit. ...

@steveboutcher803 years ago Dear fellow coach. Just a little about my background. I have been doing CrossFit for almost 13 years and have been running my own CrossFit gym for 10 years. I have done martial arts (Ju-Jitsu and Muay Thai) for over 20 years. I also did bodybuilding for 15 years (competed twice) and powerlifting for 3 years. I have incorporated regular kettlebell training sessions into my workout regime weekly for the past 4-5 years. You seem like an intelligent guy, but you really miss the mark in several ways in this video. May I suggest you stop reading so many reports and studies and rather get yourself in touch with an experienced, quality CrossFit coach. Are there bad CrossFit coaches out there? Absolutely! Are there bad kettlebell coaches out there? Absolutely! Are there bad martial arts instructors out there? Absolutely! Are there bad powerlifting coaches out there? Absolutely! Are there bad... Blah, blah, blah fill in the blank... But you get the picture? For some reason, somewhat unknown to me, many people, apparently yourself included seem to think that the goal of a CrossFit workout is total exhaustion and annihilation of the body... This is COMPLETELY wrong in most cases. It is kind of ironic given that most people, again, including yourself apparently know little to nothing about CrossFit coaching and programming. In this very video, you yourself are demonstrating several movements with the kettlebell. You show the single-arm jerk exercise... Do you believe that this is extremely dangerous? Of course not! When done correctly and with good technique, most people can do the KB jerk safely. We do snatches and long cycles as well. At our gym, the highest priority above all else is quality of movement and safety. Yes, we do have some high-intensity workouts, but they are, for the most part, performed with low-skill exercises. We have adopted the mentality of: "Intensity is earned, not given!" This means that you must earn the right to perform a movement at a high intensity... You do this by demonstrating time and time again that you can perform the movement skillfully and correctly at a higher heart rate or under fatigue. I cannot speak for all CrossFit gyms out there, but at our place, we do a lot of workouts purely for quality, not for time. We encourage our athletes to only train/push themselves as hard as they can maintain a high quality of movement. Quality first... Always. Competitive CrossFit is a whole different game altogether. I am talking about the average Joe/Jane looking to improve their health and fitness. I will however say one thing that could be perceived as negative about CrossFit. CrossFit, like many other sports or training systems, will often bring out the ego. The ego that says that I should be faster than him or stronger than her or a should do more rounds than that guy or I should run faster than her... Half of my job is taken up trying to protect people from themselves. People, in general, have huge egos. They have something to prove to the world. They attach their own self-worth and value to their ability to do and/or achieve certain things... Be it in the gym, social lives, work-related or academic. We all attach our self-worth to achievements. As it relates to CrossFit, it is often ego-fuelled efforts, so determined to be better than the next guy, that leads to injury. Pushing too hard for the glory of being the "best". We actively discourage our athletes from competing in the gym unless there is a competition. If you always compete in every class... When is it you are really training to get better? Do all athletes listen to me? No, no they don't. Some people only listen to themselves and their inner ego voice. Not so long ago I was running a class and a new member (on her second class) was taking part in a workout that included box jumps. I knew the lady was deconditioned and not in good enough shape to do box jumps. I specifically told her she should do step-ups to a low box height so that she could build up strength in her legs and avoid the risk of injury that can occur with box jumps. I also told her to take her time and to just focus on herself and doing the movement correctly. We started the workout and the lady proceeded to do step-ups. about 30 seconds later I caught sight of her from across the room. She had started jumping up onto the box. I quickly made my way towards her, but I was too late. She didn't have the agility to make the next rep and smacked her shin again the box and fell backwards. She was bruised and clearly upset but wasn't badly hurt. I told her not to continue the workout, partly to avoid further injury, but also because she wasn't willing to follow safety instructions. When I asked why did you start jumping when I told you to do step-ups??? "Everyone else was jumping and I wanted to see if I could," she replied. You see, people are people and we all have egos. I know people who have broken limbs doing Thai boxing... I know people who have fallen off horses and gotten brain injuries. I know people who have had career-ending injuries doing competitive kettlebell sport. I know people who have injured themselves doing... You name it, just about every athletic activity. A lot of the so-called dangerous "CrossFit" Workouts, such as the one you show in this video "Hard Cindy" or similar, are usually reserved for people that are far... far fitter than you or I. They are reserved for people who have trained their bodies to a level that can easily perform such efforts. One man's medicine is another man's poison. The key to success is the dosage. You don't give a newbie a dangerous, high volume, high skill workout. This is a recipe for disaster. Give the newbie his correct and appropriate dose of medicine and he will get well and fit. Most of my job as head coach is scaling and finding appropriate alternatives to the different fitness levels of our athletes. Any good CrossFit gym knows how to do this. It takes time and humbleness to learn, but we always say, "don't teach what you don't know." It's better to be safe than sorry. I have no idea where you are getting most of your statistics from that you use in this video, but they are seriously foreign to me, at least from my experience at our gym. You also read out loud "The inclusion of rest intervals is not common practice in CrossFit prescriptions." Really? How would you even know this? We use regular rest periods and intervals and workouts for quality. My friend this is total BS... But again, I cannot speak for all of the 15000 plus CrossFit gyms around the world, but apparently, you can? My friend, I can understand why people may think CF is dangerous, and you know what... It can be... Just like kettlebell sport and/or any other sport or workout system. If done incorrectly with too much intensity any sport is dangerous. I personally haven't visited all 15000 CF gyms in the world, so I cannot speak for them or know how they program their workouts. That would be pure arrogance and ignorant. Also, just to make it clear... I see many people thinking (including yourself maybe) that CrossFit is all about doing workouts against the clock as fast as humanly possible. Really??? This isn't the case for the most part. Timed workouts are a part of the program, yes, but people often ignorantly think that this is the core of our training. What about all the masses of strength work we do? What about all the masses of skill work and technique development we do? What about all the work we do in classes at low heart rates for quality? A CrossFit workout absolutely doesn't always mean max heart rate and feeling like death afterward. An entire workout at a CrossFit gym could be first doing some strength work on back squats, then followed by some upper body pressing strength work, then perhaps finishing off with an EMOM of say kettlebell snatches with an emphasis on learning good technique. Lebe Stark... I love your videos and you do have some good points in this one as well, but you are way off the mark on several things. If you like, I would love to do a zoom video with you and chat about CrossFit and training in general. Let me know. All the best buddy. ... 1
