[Marvel X-Men] Does Wolverine see instant results when he works out?

His powers are obviously accelerated healing.

When you work out, you're damaging your muscles so when they repair, they also grow in mass so they dont continue to tear under similar stress.  This is why it's important to increase workout intensity and consume protine, so your body has stuff to build muscles with.

Since his muscles would repair as fast as he is tearing them, would he just continue to grow on the spot?  Could he workout for a full day and see those results at the end of the day?  How quickly could he get how big?  Could he just attempt to lift a mountain, rip his muscles under the strain, and have them instantly repair with vastly more mass?  Theoretically, if he continued  to lift things that were too heavy to the point of tearing his muscles, he could get jacked in like.... a few hours, if he wasn't already.

Honestly: yes, he would, but that would have been long, long ago. What “state” he heals to is squishy at best. But yeah. 

A couch potato suddenly getting his regeneration would immediately feel amazing, have literally infinite stamina (yes, sexually too) and almost accidentally would get buff over time.
