Sit-ups are one of the oldest and most recognizable ab movements — and they still work. FitnessTracker includes this bodyweight classic because it builds real strength in the abs, hips, and lower back, while improving posture and control.
Instructions
- Lie on your back with your knees bent and feet anchored under a stable object or held by a partner.
- Place your hands behind your head or cross them over your chest.
- Engage your abs and lift your upper body until your chest is near your knees.
- Slowly lower yourself back to the floor under control.
- Repeat for your desired number of reps, keeping each repetition smooth and steady.
