[Deadpool] Lifting weights.

Deadpool has some godly healing factor. If one day he decides he wants to get bigger and started lifting weights? Will his enhanced healing factor stop him from increasing any muscle mass since lifting weights involve tearing muscle fibres and letting it recover for muscle growth? Or his healing factor makes it even easier for him to grow his muscles since he can make more gains in a day than a regular human do in months.

The latter, it makes it easier for him to gain muscle mass. Same with Wolverine. He heals new muscle mass faster than any human so he can bulk fast, and bulks regardless of caloric intake, as his regeneration isn't bound to diet, the mass generates spontaneously.

I can't remember if it's still canon to 616 but IIRC there's a brief explanation from as early as the late 1960s that *Homo Superior* in general tend to have at least a low-level healing factor which in part explains why even non-athletic heroes tend to be built. They're just very naturally prone to maintaining a good physique, so long as that physique doesn't contradict their powers. The same explanation also claims that *Home Superior* tend to naturally skew more attractive than humans (powers allowing), which is why so many mutants are good looking.
