When the climate is warm, there’s nothing quite like going for a refreshing swim at the local pool. To add to the benefits, you can use it as an opportunity to work on those stomach muscles. The water gives natural resistance, making the pool a good area to do tummy workouts to flatten out that tummy. Despite the greater resistance water has than air, aquasizing is low-impact, meaning less strain on joints. Try out these exercises next time you take a trip down to your pool. Keep in mind, consult your doctor before starting a new workout routine, and constantly warm up properly to avoid injury.
