Roller Reverse Crunch: How to Do It & Muscles Worked

The roller reverse crunch is an abdominal exercise that uses a roller held between the feet to increase resistance and challenge core stability. It targets the abs and also engages the hip flexors.

How to do the roller reverse crunch

  1. Step 1: Lie flat on your back with your arms extended straight above your head and your legs straight out in front of you.
  2. Step 2: Place the roller between your feet and grip it with your toes.
  3. Step 3: Engaging your abs, lift your legs off the ground and curl your knees towards your chest, rolling the roller towards your body.
  4. Step 4: Pause for a moment at the top, then slowly lower your legs back down to the starting position, rolling the roller away from your body.
  5. Step 5: Repeat for the desired number of repetitions.

Sets, reps and programming

Suggested sets, reps and rest for the roller reverse crunch by training goal
Goal Sets Reps Rest Effort
Strength 3–5 3–6 3–5 min 1–3 reps in reserve
Muscle growth 3–4 6–12 2–3 min 1–2 reps in reserve
Muscular endurance 2–3 12–20 1–2 min 1–3 reps in reserve

Ranges follow the ACSM position stand on progression in resistance training. Muscle grows across a wide range of loads when sets end close to failure (Schoenfeld et al., 2017), longer rests between heavy sets support strength and size (Schoenfeld et al., 2016), and stopping a rep or two short of failure works about as well as training to failure (Grgic et al., 2022). Estimate your working weights with the strength calculators.
