How often should I do sit ups?
Asked by futurebeauty on Dec 12, 2008
Train your abdominal muscles every other day or 2 – 4 times a week. Do 3 – 5 sets of maximum repetitions with a 30 – 60 second rest in-between a set. A rep is a completed motion done once and so one sit-up is one rep. A set is the number of reps that you do before resting. A beginner may start with 10 - 15 reps for a set. The perfect crunch has replaced the sit-up, which, when done incorrectly, can lead to injuries of the neck, back and shoulders. To strengthen the abs, target all of your core muscles.

The side effects of allergy medications keep some people from using them. Natural remedies can be a great alternative, but some are more effective than others.
