i currently am doing a 3 day FBW, since i am trying to gain mass and I like the idea of training with lots of heavy compound exercises. However i like going to the gym and i have lots of free time to do so. I feel like i could be making even more gains by taking advantage of my extra time to work out by moving to a 4 or 5 day routine.
so, will i be able to put on more muscle by increasing the number of days i work out, or are 3 intense days more than enough stimulation?
3 intense days is more than enough. Don't reinvent your working wheel when it's working for you.
