Normally about 4 sets per exercise with about 4-5 exercise's being completed. The more volume the better. High reps 10-15 with short rests (less than 1 min between sets) stimulates the release Growth hormone releasing factor which causes the release of growth hormone. This helps in glycogen storage and protein synthesis. You can still gain some strength by this method, but size (volumizing effect) and muscle endurance are the main results. Its good to mix it up. A month or so with hypertrophy, then go to strength..Mix it up...
During aerobics, you will burn both fat and carbs. But, you can actually target one more than the other according to VCO2 exchange machines. When your intensity is 80% and higher (according to the karvonen method), your geared toward burning carbs, but you will burn calories faster. When your around 60-75% of your Max HR, with longer durations (greater than 30 min), you burn more fat. If you want to maintain mass, but cut some fat, I would recommend moderate pace for a long duration (around an hour at
4-4.5mph with about a 7-12% grade (be careful, this grade is hard on the knees) or the ellipitcal set at around 9 on the resistance for an hour. Keep your hear trate controlled around the percentages. (remember, 20 minutes is about the time when you START primarily burning fat)
An easy way (not karvonen) to figure out your needed heartrate is take your age minus 220 and multiply by 60, 70, 80, or 90% (change them to fractions) and the result is your target heart rate.
