I believe I have a bizarre but unique question.
I would like to know if its possible to increase muscle mass without increasing (Or while minimizing) muscle size increase (Maybe by increasing muscle density if possible). The reason I ask is I would like to reach a much heavier weight but without bulking up (As much as physically possible).
If this is possible, can strength gain be maximized as well (As in can strength be increased without increasing muscle size.) I've read multiple times that this is usually done through low rep high weight exercises.
Note: I am not talking about losing fat while gaining muscle to keep the same weight. Nor am I talking about increasing strength while maintaining the same weight.
Instead I am talking about increasing your weight with minimum bulking (Ideally while also increasing strength).
Finally can this be done using body weight? (At least in the beginning)
