"the year is 2095 and it's my first day in 6th grade. Miss Mable is handing out our steroid candies so we will grow big and strong then have a 'bank' of muscle memory to rely on in our secondary and tertiary life stages."
This is probably also why my chest is overdeveloped compared to my back, because I was doing hundreds of pushups back then while neglected any sense of balance sadly.
Except heavy weight bodybuilding of course where it is too obvious.
The vast majority of people could get away with real food and regular training to reach their actual fitness goals; not many people want to be as big as Ronnie Coleman. But if you do want to be a competitive bodybuilder in America, you're going to need more than supplements.
The fitness industry also did a great job of convincing people that supplements are the cause of, not an aid, to muscle growth. I was in the ER once for a broken finger, and the poor kid next to me had been to the ER twice that month for stomach pains, and it turned out he had been sitting at his computer slamming down 10 protein shakes a day and doing nothing else. Just one of many similar anecdotes from when I worked in the industry.
Do we know if devices like Emsculpt work to improve bone density? I don't know how the cell-signalling cascade works for putting more calcium-mineral matrix in bones so maybe muscle contraction repetition initiates the cascade, or maybe it's insufficient by itself?
Full range of movement training also works to shift lymph back toward the left subclavian vein where it joins venous circulation.[1]
The lymphatic system is the primary cellular waste product transport system, and an immune organ in it's own right.
From what I read about the place this is a significantly understated feature of exercise and plays a key role in the idea that bed rest is massively counter productive in convalescences and post surgery recovery / outcomes.
The size of the squat rack is another issue however.
Has anyone done a longitudinal study in this area?
