Alternate Heel Touchers
You lie on your back with knees bent and reach side to side to touch each heel, one at a time. This targets the obliques — the muscles along the sides of your abdomen — without putting any strain on your neck or lower back. It's a gentle, controlled way to build core stability that supports everyday movements like reaching, twisting, and getting up from a chair.

Form cues
- 01
Lie on your back with your knees bent and feet flat on the floor, about 18 to 24 inches apart.
- 02
Rest your arms straight down by your sides, palms facing inward toward your legs.
- 03
Press your lower back gently into the floor so there's no gap between your spine and the ground.
- 04
Lift your head and shoulders just 3 to 4 inches off the floor — think of it as a small crunch, not a full sit-up.
- 05
Slide your right hand toward your right heel, reaching until your fingertips touch it, then hold for one second.
- 06
Return to center, then immediately slide your left hand toward your left heel and hold for one second.
- 07
Breathe out as you reach to each side, breathe in as you return to center.
- 08
Keep the movement slow and deliberate — let your side muscles do the work, not momentum.

Common mistakes
Lifting too high off the floor — if your neck feels strained, you're coming up too far; only your head and upper shoulders should leave the ground.
Pulling on your neck with your chin — your hands should stay at your sides, not behind your head; if your neck aches, you're using it instead of your abs.
Rocking your hips side to side — your lower body should stay still; if your feet are lifting or shifting, slow down and shorten your reach.
Rushing through the reps — if you can't feel a gentle squeeze along the side of your torso, you're moving too fast to get the benefit.
Holding your breath — if you feel your face getting red or tense, remind yourself to exhale on each reach.
Scale it
Easier and harder variations
Easier
Move your feet closer together, about hip-width apart, so the reach to each heel is shorter and the movement requires less side-to-side range.
Use this if the full reach feels like too much strain or you can't quite touch your heels yet.
Harder
Move your feet farther apart — up to 30 inches — so you have to reach farther to touch each heel, increasing the demand on your obliques.
Try this once you can complete 3 sets of 12 reps with good control and no neck tension.
Note
If you have lower back sensitivity, place a folded towel or thin pillow under your lower back for light support, and reduce your range of motion so you're only reaching a few inches to each side.
Use this if lying flat causes discomfort or if your back tightens up during the movement.
