Nonsense.
Taking breaks between resistance exercises is the most efficient way to build strength. Once you develop strength, then you can consider reducing the interval between sets to build strength endurance.
Most strength training experts recommend 3-5 minutes between sets done at maximum intensity. This gives more than adequate time for the targeted muscles to recover adequately. A set ends when perfect form cannot be maintained. Working in poor form or with muscular fatigue puts excess load on smaller stabilizer muscles and sets the stage for injuries to joints and ligaments.
Focus on perfect form, slow reps and maximum intensity. Not heart rate. Not keeping pace with the DVD. Until you reach weights that challenge you, you may find that you need less than 3 minutes to recover for the next set.
This is what I had heard in order to build size/strength. As far as it being against the P90X philosophy, I think that's just because the program is geared toward maximum calorie burn, & the breaks would gear the routine less toward burning calories & more toward size strength.
I took 2 min breaks between every move in "Shoulders & Arms," & I noticed I was able to do higher weights & more reps throughout the exercise than without the breaks. It took about 2 hours to finish, but it felt more efficient for size. Can someone confirm for sure that this is a more practical way to lift for size?
