Dr. Mel Siff praises gymnastics:
There are few sports which offer as many variations of upper and lower body plyometric action as gymnastics...Gymnastics involves complex jumps, depth landings from certain apparatus, depth jumps, plyometric rebounds, ballistic actions in three dimensions, training of reaction time, short sprints, explosive trunk activities and numerous other actions that together are unrivalled by entire volumes on ‘plyometric training’. Add to this the eminently demanding motor skills and great accelerations and we can see that gymnastics offers an impressive system of strength training involving maximum power development, high Rates of Force Development, powerful eccentric loading, intensive slow and rapid isometrics, true core stability (in free space, not attached to the floor) and “functional training†of many aspects of human movement.
... there are those who consider weight training to be the only effective form of strength training. Does not gymnastics also qualify as a complex form of highly technical strength training?
Of course, this now leads us towards the inevitable question: :†Is it at all necessary for gymnasts to do any additional weight training?â€

Dr. Mel Siff explains why you need to do backbending:
It is not only exposure to a stressful action that can cause injury, but also religious avoidance of so-called dangerous actions (which might occur during actual sporting conditions). One cannot expect the body to cope with the immense structural and functional demands placed on the body in sport unless one methodically conditions the body to cope with progressively greater structural and functional stresses.

Is it possible to dispense with weight training?
In fact, even in American football, one could probably dispense entirely with the weights gym, all free weights and machines, and substitute a mixture of track and field and gymnastics activities coupled with a well-chosen mixtureof martial arts forms (karate, wrestling, boxing, ultimate fighting, Taekwondo, judo, aikido, sumo and TaiChi) – and produce equally phenomenal players....
I have little doubt that a Martial arts-Track-Gymnastics (MTG) program would produce NFL players, for example, who just as proficient as their weight-trained counterparts, all other supplements, game practice and rewards being equal – and at much lower cost.

This last comment by Siff interests me because I have, pretty much, come to this very conclusion myself (that a combination of martial arts, gymnastics and track create great athletes). I do gymnastics, BJJ, and sprinting/jumping, but also add in a couple weighted exercises such as squats and hip thrusts. I really don't do any weight training other than that anymore. Not that I have anything against weight training in the slightest, or that I am training for American football.
