Hello,
@North Coast Miller
As far as pistol goes, maybe escalating density can be an alternative.
Indeed, we are supposed to hit more reps in the same time frame. So you get more work done (TUT) in the same amount of time...then we can consider we get stronger that way. Plus, in general, we only perform this during 5-7 minutes so eventually, there is not "that much" reps (but the HR may rise a little).
EDT is something which works well even with bodyweight only training to build muscle (at least for me). Did you already try ?
Kind regards,
Pet'
