lol you honestly think bolt does some hardcore ab work? and really heavy weighted abs?
The core/hip flexors are the powerhouse to limb speeds (IMO). Not glute, quad & ham strength (Squats etc).
The core’s primary job is stabilizing you
If your running sub 10’s, your qualified to say that.
The CFTS involves tons of high rep ab work, not heavy abs. From what I’ve read about Powell’s training, it’s been some of the basic ab stuff + some med ball ab work. Bolt’s training has had a quick mention of core work. John Smith did not use heavy abs (at least not primarily) in his program.
How many sub 10 guys do you know, that are doing tons of heavy ab work/hardcore core exercises? and… they have made improvements in their speed only due to that?
For the general, yeah squatting 400-500 will probably make them run faster. But from what I’ve witnessed this isn’t the case.
It’ll make the muscles involved in sprinting, stronger. Just over a long term, it will help in speed.
Just too conclude. I was doing weighted ab work for almost 2 years straight & I was in denial all along believing I was strong there.
how much did your time drop before and after? I’ve done heavy abs too, and saw no noticably more improvements than I did doing no abs lol. Same goes for squats basically.
but hey… if it works for you, keep doing it.
