Surprising result of training STRENGTH & CARDIO concurrently…

I’m often asked what the best way to decrease body fat while maintaining muscle mass – diet or cardiovascular exercise (low intensity steady state).

Below are a few articles which show if you do low intensity steady state cardiovascular exercise and strength training at the same time, you lose the benefits of both!  Training for strength and cardiovascular endurance (via low intensity steady state cardiovascular exercise) concurrently decreases gains in:

  • Cardiovascular fitness,
  • explosiveness,
  • strength and
  • muscle mass.  1,2,3,4

So, if you have a desire to lean out and shred while maintaining your hard earned muscle mass,  do so without low intensity steady state cardiovascular exercise, and focus on an impeccable diet.
