Decline Sit-up and Russian Twist
The Decline Sit-up and Russian Twist combines core strengthening with rotational movement.
- Secure your feet at the end of a decline bench.
- Lie back and perform a sit-up, bringing your torso towards your thighs.
- At the top, twist your torso to one side, engaging your obliques.
- Return to the starting position and repeat on the other side.
How to perform the Decline Sit-up and Russian Twist
- Set up. Set up in a stable, balanced starting position appropriate for the Decline Sit-up and Russian Twist using your body weight.
- Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your abdominals.
- Reset. Reverse the movement under control and reset between repetitions, keeping your form crisp on every rep.
Coaching cues
- Move with intent — every rep should feel deliberate, not rushed.
- Drive force through your abdominals rather than momentum.
- Keep your breathing steady: exhale on the hard part, inhale on the reset.
Common mistakes
- Using too much weight and losing positional control.
- Cutting the range of motion short and missing the target muscle.
- Letting your spine round or hyperextend instead of staying neutral.
