By having at least a days rest in between direct ab workouts, you are allowing the midsection to recover and grow just like your other muscles. It is best to train your abs after your regular workout, and stick to the time frame of 10-15 minutes at most. You do not want to spend 30 minutes doing straight abs exercises. Simply choose 2-3 exercises and cycle through them 2-3 times each. This will be far enough to get you a great workout.
Vigorous-intensity exercise may be too much for someone who has been inactive, so obese individuals should start with 150 weekly minutes of moderate-intensity exercise. This will help slow or stop weight gain, but to lose weight, obese people will need to get more exercise. The ACSM recommends that obese individuals gradually work up to 250 minutes of weekly moderate-intensity exercise to increase weight loss. This can take any form: for instance, five 50-minute workouts per week or seven 37-minute workouts a week. Resistance Training Obese individuals should follow the same guidelines as other healthy individuals for resistance training, working out all major muscle groups twice weekly.
