Walking:
Walking is one of the best exercises to keep fit. A 15 minute walk can be quite helpful.
Aerobics:
Manage your food craving by working out. Even a 20 min. aerobic exercise does wonders.
Posture:
Improve your posture. Walking with a correct posture makes you look taller and slimmer.
Crunches:
You do not need to go to the gym and work out to build up muscles. 100 crunches a day, can give you great looking abs.
Say no to elevators:
Walk up and down the stairs.
