Increase your daily exercise to 20 minutes.

Do not try to workout for 40 minutes one day to skip another day. Steady exercise is the most beneficial. Do your best to keep to a daily schedule.

Try working out at different times during the day. Some people find that exercise first thing in the morning helps them energize for the day. Others find that evening workouts help them de-stress after a day at the office or dealing with the kids.

Try incorporating light weight training into your workouts. Add hand weights and arm curls to your walks to help tighten arms and tone your chest muscles.

Add some ankle weights to your walking or swimming to improve lower leg strength and tone leg muscles.
