Might be some truth to that. I use resistance stuff and just use gravity for the most part, as opposed to machines. I have always had my own poor man's gym at home ha. Like filling milk jugs with water and using them as lifting weights. Going to the gym and actually having professional trainers, spotters, etc is probably better. Getting out into the world and socializing is probably healthy in and of itself. But since I'm usually too petrified to go to a gym I figure trying my best at home is better than nothing.
