Earlier quoted context omitted.
I also build muscles in VR training and I've done a lot of stronglift so I know what progression is like. Pistol Whip is great for building leg muscles. Imagine doing that one more squat you didn't think you had in you when in the squat rack. In Pistol Whip you do that 20 times without noticing. You don't need progressive overload to build muscles. High rep sets should not be underestimated.
The lower body musculature is too large to be effectively stressed by bodyweight exercise in people fostering any decent level of fitness, i.e., bodyweight squats don't make you stronger. Just because an exercise is hard or makes you sore doesn't mean it's effective.
Do you think this is the difference, the mindset we have in our training.
