1. When your goal is to burn excess body fat, simply rest for only 20 seconds in between sets. This will keep your heart rate elevated the majority of the time.

2. Blood sugar and insulin response is key when trying to gain muscle or decrease body fat. So you want to eat every couple hours in order to keep your blood sugar stabilized. If you eat only a couple of times throughout the day, your blood sugars will be up and down, which leads to non-consistent insulin levels, which leads to excess body fat storage.

3. Recommended repetitions based on your goal:
Tone Up = 12-15 reps
Increase size = 8-10 reps
Increase strength = 1-6 reps
