Doing nightly situps will help build your abdominal muscles and strengthen your core. The situp is an easy, equipment-free exercise that works out your hip flexors and core muscles. Try doing your situps at night if you have problems sleeping. Strength exercises, such as situps, done at night or during the day are effective in improving the sleep quality.
The situp is a fundamental exercise in fitness, strengthening the core muscles of your body. You use these muscles in many movements and athletic activities. Situps are done by laying on the ground and pulling your knees up until they are bent at a 90-degree angle. Place your hands behind your head and raise your upper body until your head is parallel with your lower back, then lower your upper body back down until your shoulder blades are on the ground. This is one repetition of the situp.
While there are no specific benefits to doing situps right before going to bed, committing to a regular situp routine will make it easier to do situps in the long run. Doing situps nightly or every other night is one way to do this. When performing situps at night you will probably want to wait an hour or so after eating your last meal of the day before engaging in situps, otherwise you may upset your stomach.
Establish goals with your situp plan. If you're doing situps simply to look and feel better, you can train more leisurely at your own pace. If you are training for a physical fitness test that emphasizes reps, time your situps with a stopwatch in order to create a pace you need to achieve. If you are doing situps simply as an aerobic activity, or as a means to burn calories and build muscle, try for a slower situp dedicated to maintaining correct form. With these situps, ease your upper body slowly back to the ground, achieving a burn in your abs on the way down.
While the situp is a great exercise for strengthening your core, always make sure to do them with proper form. Do not curl your back or pull up on the back of your head. These motions can strain and damage your spine. If you have trouble keeping your feet down during situps, you may want to find a partner to hold your feet down for you, or hook your feet under an object such as a couch or dumbbells.
