After level scéances avoid working the opposite muscles, the better
it is a big muscles and small by scéances. eg triceps pecs, biceps
back, shoulders trapezius ... we must also know that muscle needs rest
to build so avoid working the same muscles two days affillé! I advice
you in your scéances mass gain is that your series must be short but
then m max of recovery.
the thing to avoid the mass gain is the cardio if you push your heart
has too high pulsation minute gonna dip into your muscle you can run
but slowly example, a calculation is also to know that she has
pulsation must be stabliser to dip into fat and not in the muscles. ^
you must be able to talk when you run.
