Is masturbating

How long does it need to be to qualify for 'circuit' training. Would 6 inches qualify as a circuit

VG it has to be at least 20 mins. for it to be aerobics.

So anearobic it is..

That will build that (Lg.) muscle if less than 20 mins. ..

If you do it durning your workout session it would be circuit training.

Either way very good thing to do..

I agree, it is anerobic. To develop/maintain symmetry, be sure to switch hands every workout.

If you see a guy with one forearm larger than the other, he doesn't switch off.
