Here are three ways to lose weight, including sit-ups, cycling and V-shaped exercise.

♀? sit-up

Lie flat, bend your legs, put your hands behind your head, lift your upper body with your lower abdomen as the midpoint, and retract your feet until your elbows touch your feet. Repeat the above steps and do thirty.

♀? Ride a bike

Lie on your back, bend your legs and lift 45 degrees. Your legs alternately extend and contract forward. Take a step forward and keep your feet at about 30-60 degrees from the ground. Hold for 5 minutes.

Sit up straight with your feet together and straighten your body forward. Lean back and lift your legs together. Hold the action for 10 second, and repeat the above action for 10 times.
