I should've written more explicitly: bodyweight squats don't make people who harbor a decent level of fitness stronger. Like any novel stimulus, they will make you stronger for a short while and then it will stop once you've adapted.
It's pretty obvious that the target audience for VR exercise is not 'people who harbor a decent level of fitness'. You're looking at the wrong baseline.
I'm curious about the precise interpretation here. Are you saying increased strength be lost and I will return to baseline before I started exercising? Or are you saying I will get a certain amount of increase and I will maintain it, but it will plateau there?
Because I'm just fine with the 2nd scenario. The first would be weird and contradicts my experience (nearly 2 years in ...).
Complete nonsense.
