Some of these exercises fly in the face of current Sport Science Practice. Some of them being strongly discouraged. Some do, and some dont. The truth is that "Modern sport science" Is ever changing. When I first started training in sports med (read rehabilitation of injuries and sports training), we all thought that Plyometrics were horrors to the joints and should be avoided like politics! However as time went on we learned that they were good and are now a staple of most training regements for high end athletes. We also thought that long dull jogging was the best training for cardio and for weight loss....we now know that Tabata or interval training seems to work better and is easier on the body....Read knees and legs. So, lest not judge all these with one brush of paint eh! Deep squats load the knees. As does tying weights to the feet which also tends to over exend the knee joints and effect the knee cartlidge. While Deep Squats do load the knees, one can do them successfully and not worry about harm to the legs...if you are 20 and in good shape go for it....for us old gits...watch what you do with deep squats lest you want a real fancy walker for chritmass! Having said that....see coment about plyos! Also, the lad with the weights on his feet...the Geta....will NOT be hyperextending his knees anytime soon, the kicking is all done slowly. I have seen and been on course and have a pair of these bad boys, however Have never seen the trick with the old belt! If done slowly this exercise is great for hip flexors and quads. the main idea is to go slow and make the muscles work really hard...and they do! Now if you tried to do a Mae Geri fast with these on you will hurt yourself...so again, its not a question of a bad exercise....its a question of poor performance of a good exercise...which we can accomplish with any exercise. Unsupported situps/leg raises pressure the lower back and are banned on some sports courses. SPOT ON WITH THIS ONE. If you do them with unbent knees you will more than likly hurt your lower back, Granted if you have a strong lower back and work it as much as the abs then you may avoid it...but chances are better that you will do your back some harm. Why not bend knees and take your back out of the issue? I am all for core training, hell I do it twice a week at home just to keep my back strong, and I suggest hitting your sides, abs and back with equal reps. But yes, like Garage said...bad bad idea here....till I am pronion wrong! Balistic/Bounce stretching is considered ineffective. It is good to consider how these exercise work rather than just copying to reduce the risk of long term injury. Oh yawn I am boring myself. Actually Bounce stretching is not considered ineffective, its called Balistic stretching and it is great for stretching...as long again as you are in shape. Of the three kinds of stretching however it appears to be the least effective for long term flexibility improvement...with PNF stretching as the best followed by Static stretchign and then Balistic. The biggest issues with Balistic is the level of danger in damage to ones connective tissue and the chances that it might harm you more than help...but same with the other two kinds! I agree that they offer great ideas that one should play off of. For instance if you wanted to make the squat jumps safer, dont go as low and think of straightning the legs more than the student in the video does. All of these exercises can be made more effective or more safe...but you just dont go into it blindly! i would much rather see someone thinking like Garage here does than just jumping into the exercises that .......wait.....scratch that....everyone should be just jumping into the exercises as advertised.....I do need new clients and I am sure my fellow therapists in the UK can use the work!

Truth is that most poor joints are a combination of issues and poor training, bad genetics, being a bit heavy, and various other habits and situations......

I have to ask slow mae geri with weights on develops slow twitch muscles and bulk. Would this not quite fit with the speed and strength you are looking for in kicking? Here is were the Sports Science tends to get muddy with "street science"....ever wonder why sprinters do weights...why gymnasts do weights...why boxers and fighters do weights? Well its because you NEED BOTH. the proper training is to mix pure strength training with explosiveness training. Then you have power! However, their are different schools of thought. I have trained with coaches that BAN Sprinters from doing weights and I have worked with Coaches that set up very detailed weight training programs. It is a difference of thinking, my thoughts are after years of study and watching pro-coaches teach speed athletes that doing weights slowly for power and then plyometic type explosiveness drilling does work...and it works very well. I tried it in my youth and found my Karate was very good because of it. I was fast and explosive and hit hard...However I really do wish I spent more time focusing on techniques and strategy over use of speed and explosiveness...those things are going away as I get older and I am left with tree trunks for legs and lots of strength...but speed does evaporate with age in most cases!

Got that right....I also now MUST warm up and down or I dont get the option of complete movement the next day! I went running the other day on a tread mill.....seeing as it actually hit minus 34 the other day...and the hamstrings are Singing to me today!

I think that we would all agree that Karate in many Dojo - even know - is woefully neglectful of educating themselves about research based advances in sports science IMHO such a waste! hopefully people like kensei can help us all to access this stuff - and not only help our own bodies but those we teach
