Sit-up benches rest at an incline to make sit-ups more challenging and effective. Sit-ups done on an incline bench work the rectus abdominis, obliques and hip flexors. Performing sit-ups using a sit-up bench is an effective way to achieve six-pack abs.
- Warm up before doing sit-ups.
Perform five minutes of cardio exercise to warm up your muscles before starting your sit-ups. Stretch the abdominal muscles with a few trunk rotations.
- Set up the sit-up bench
Set the bench at your preferred angle of incline. The steeper the angle, the more you get out of the exercise. Start with a 30-degree angle if you aren't sure how much you can manage.
- Get your body in position
Sit on the lower end of the sit-up bench. Tuck your feet under the supports or foot strap at the upper end. Lie down on the bench with your back flat and your knees bent at a 90-degree angle. Place your hands behind your head.
- Perform the sit-ups
Lift your torso toward your feet, exhaling as you do so. Touch your elbows to your knees without bending them forward. Lower yourself slowly back to the sit-up bench, inhaling as you do. Repeat the sit-ups until you have reached your goal or hit the point of exhaustion.
