Funny thing you say things like that. Doesn't seem to be too popular around these parts to do BWE.
My personal goal was to be overall fit, and found that variations of pull-ups and push-ups are the best mediator at achieving that goal. But, I keep getting requests to "lift weights instead", rather than keep up a solid body weight routine.
I believe a good strength to body weight ratio and having LEAN muscle growing, rather than bulking is more to my suit and tastes. I may give this 100 push up challenge a try. I dunno how many I can do, but I'm estimating around the 40 mark before my arms feel like popping. Would be a pretty sweet goal to do 100.
There popular with me, and I could careless whether they are popular with someone else or whether they think I should do them: I know best through educating myself.
I train hard and I train heavy with weights. However, their are times I plan BWE's into my weight training program, to recruit the fibers that: the heavy weight does not. Additionally, I personally want some endurance in my muscle.
BWE's became especially effective a few months out of going back to the Police Academy for the second time. And, training in a manner in which I was going to be "tested" was the essential factor. Before going to the academy (and still training heavy), I was able to push out over 100 push-ups: In one go, and well over 300+ sit-ups (among many other exercises as well). The entire driving force was: They weren't expecting this from a 46 year old among many in their prime. I was going to set them on fire. You ought to have seen their faces. LOL.
I owe A LOT to BWE's and band exercises, especially when I first began my goal path to lose tissue. I learned real fast, that while my muscles were more than willing to rock the heck out, my tendons and joints were not so willing, and needed additional recovery time. And BWE's, certain types of exercises (that dont even make the list on many persons training platform), shoulder girdle exercises, and certain band implementations, played a key role in their active recovery. Now, I dont have ANY joint or tendon pain, and I push it HARD......and this is an understatement of the frigggen year.
Sometimes I will put BWE's in-between weight training exercises, that I term as FreeForm and include an "active rest" period.
For example:
Bench Press is 3 sets progressive tier, with 1 minute rest (when the former rest from last workout was 2m). After the first set of the Bench Press, I push out as many push-ups I can during the first 30 seconds of rest, and then rest the remaining 30 seconds, and repeat for 3 sets. Sometimes I add in dips, push-ups from the hand stand position, etc.
