20 minutes of medium intensity is perfect for me during the bulking phase, not to burn existing fat but merely preventing addtional fat depositing while packing on muscle. A slight extra raise in BMR is sufficient and won't hinder gains....
More than that will hinder serious gains for me, less than that will pack on mass, but with 20 minutes it's quality mass if you know what i mean......
40 minutes post-workout cardio while in the cutting fase. Provided you do take the proteine shake immedialtely after weights, your pre-elevated BMR can profit from the additional cardio to burn the fat faster than you lose muscle while cutting...
