Keep Your Workout To An Hour Or Less
When you're planning your workouts, remember that resistance training affects your natural musclebuilding hormones and adjust accordingly.
Lots of big compound exercises will help boost your natural testosterone levels; however, long workouts also boost levels of the catabolic hormone cortisol.
Keeping your workouts fairly brief but still intense is ideal for getting the best of both worlds. Sticking to 60 minutes or less is a good rule of thumb.
