Tips On Sit-Ups
- Beginners should start with 3 sets of 8 reps and progress accordingly. To intensify your routine, increase the number of repetitions.
- The key to building core strength is the breathing technique. Take deep breaths and keep the pace slow. Concentrate on contracting the muscles and holding the position.
- Start with your feet 12-18 inches from your butt and continue doing curl-ups. If it feels intensive, increase the distance between your butt and feet. This new angle between your abdominal muscles and legs will take you through a few more reps.
- To avoid the pain caused by faster sit-up movement, do a less intense variation of the sit-up with the exercise ball. This can help reduce the strain on the lower back. Keep your lower back firmly in contact with the floor throughout the movement to avoid excessive strain.
- You can also add weights to intensify your sit-up and challenge yourself. Just grab a pair of dumbbells and hold them in your hands. Weights are best added in the Jackknife version of sit-ups.
