well i want to compete in boxing ya, but i have no gym right now except for this free week.. i have to figure something out.. i mean i could just go fight in amateurs without gym access, who knows.. preferably i'd have gym access to get in some sparring/heavy bag work, that prepares the body well for boxing, without it, im just doing shadow boxing/sprints/bball dribbling/bw exercises.. not as effective :/

and since theres no Q and A do u mind if i ask random lil questions every now and then cause im still learning? first one, wats the diff between REA squats and jump squats?
ya np..
REA = reactive.. it has a freefall component, meaning, you start in standing position and then 'freefall into say, a above parallel squat position.. this results in a very brief impact, but that brief impact recruit significant motor units, because of the load on your back, you then reverse it as fast as possible.. so it has you absorbing an impact AND then overcoming it.
with jump squats, resetting between reps, there's no impact, so that extremely fast motor unit recruitment doesn't happen, but this is easier on the body, ie, it takes its toll less on the joints etc.. the only impact absorption you get is after you jump and land, but thats into a pretty tall position.. REA has you absorbing/overcoming in a lower position, really recruits the quads/hams/glutes hard.
rebounding jump squats are similar to REA, except always done alot lighter and the angle is again not as deep as REA..
REA can be done from 30-70% 1RM.. jump squats anywhere from 25-40% 1RM.
both help improve RFD, except one is a little bit more effective due to the big impact forces needed to be overcome (REA).
