You start lying flat on your back with your arms extended overhead and your legs long on the floor, then curl your torso up off the mat while bending your knees and drawing your hands down and back to touch your heels at the top. It is a step up in coordination from a standard crunch because the arms, legs, and torso all move through a single synced rep. The main muscle at work is the rectus abdominis, the front wall of the abdomen, which shortens to pull your ribs toward your pelvis. Because your hands travel down along your sides toward your heels, the obliques assist with guiding and controlling the path, and the hip flexors work to bend the knees and angle the thighs as you rise. Nothing more than a floor surface or exercise mat is required, which makes this a convenient option for home training, warm-ups, circuit finishers, or travel workouts. Setup matters more than it might seem. Lying with arms overhead and legs extended puts the abdominals at a longer starting length, so the crunch has to travel a greater range than a crunch performed from a knees-bent, hands-behind-head position. That longer range is exactly what makes the exercise valuable, but it also means rushing or yanking with the arms is easy to fall into. Move deliberately so the trunk, not momentum, does the lifting. To execute well, press your lower back toward the floor, exhale as you curl up, and think about peeling your shoulder blades off the mat one segment at a time rather than sitting straight up. As you rise, bend your knees and reach your hands down past your hips until your fingers make contact with your heels or ankles. Pause briefly at the top with the abdominals fully shortened, then lower under control, straightening the legs and returning the arms overhead before the next rep. This movement suits beginners and intermediate trainees who have already mastered the basic crunch and want more range and coordination, as well as more advanced lifters using it as a higher-rep core finisher. Keep the neck neutral throughout, avoid pulling on your head or straining your lower back, and reduce the range slightly if you feel the work shifting into your hip flexors or lumbar area instead of your abdomen. ## Instructions 1. Lie flat on your back on an exercise mat with your legs extended and your arms stretched straight overhead, biceps beside your ears. 2. Rest the back of your hands lightly on or just above the floor and take a breath in, gently drawing your belly button down so your lower back presses toward the mat. 3. Begin the rep by exhaling and curling your head, shoulders, and upper back off the mat, leading with your ribs rather than your chin. 4. As your torso rises, bend your knees and pull your heels in toward your hips so your feet are flat on the floor close to your body. 5. Reach your hands down along your sides and back toward your feet until your fingertips touch your heels or ankles at the top of the crunch. 6. Squeeze your abdominals hard for a one-count pause at the top, keeping your neck relaxed and your gaze up toward your knees. 7. Lower your torso back down slowly, reversing the path, and straighten your legs as your shoulder blades return to the mat. 8. Reset your arms overhead and your legs long, take a breath in, and begin the next repetition without bouncing off the floor. ## Tips & Tricks - If your heels drift too far away to reach, pull your knees in a little more at the top rather than rounding your lower back forward to chase them. - A common mistake is jerking the arms down to create momentum. Your hands should follow your torso, not drive it, so the abdominal muscles do the actual curling. - Keep space between your chin and chest. Holding an imaginary apple under your chin keeps the neck from doing work that belongs to the abs. - Exhale forcefully as you curl up. Emptying your lungs at the top lets the rectus abdominis shorten fully and makes the crunch noticeably harder. - Do not slam your legs flat on the way down. Extending them slowly keeps tension on the abdomen and protects the lower back. - If your lower back arches off the mat during the setup, shorten the starting position slightly by bending your knees earlier or placing your heels on the floor from the start. - The pause at the top matters more than a higher rep count. Two seconds of contact with your heels beats ten fast, sloppy touches. - If you cannot reach your heels at all, touch your ankles or shins instead, and work on the reach over subsequent sessions as flexibility and control improve. ## Frequently Asked Questions ### Which muscles does Crunch Heel Touch work the most? The rectus abdominis across the front of your abdomen is the primary mover, since it curls your ribs toward your pelvis. The obliques help guide the reach toward your heels, and the hip flexors assist by bending the knees as you rise. ### Why does Crunch Heel Touch start with arms overhead and legs straight? That position lengthens the abdominals before the crunch, which increases the range the muscles travel through compared to a standard crunch. It also requires coordination, since the arms, legs, and torso all move together in one rep. ### Is Crunch Heel Touch suitable for beginners? It is a reasonable second-step core exercise once you can perform basic crunches with clean form. If the full range is too demanding, keep your knees bent from the start and reach to your ankles or shins instead of your heels. ### What is the most common mistake in this exercise? Swinging the arms down hard to generate momentum so the torso flops up. The curl should come from your abdominal muscles contracting, with the hands simply traveling to meet your heels at the top. ### Should I sit all the way up during Crunch Heel Touch? No, the goal is a crunch, not a full sit-up. Your shoulder blades and mid back lift off the mat while your lower back stays grounded, which keeps the tension on the abdomen rather than shifting it to the hip flexors. ### What can I use as a substitute if I cannot reach my heels? A standard crunch with knees bent works the same primary muscles with less range, and a cross-body crunch or reverse crunch also trains the abdomen through a similar curling pattern. Heel touches to the sides from a knees-bent crunch position is another lighter option. ### How many reps and sets of Crunch Heel Touch should I do? Two to four sets of 10 to 20 controlled reps works well for most people, either as part of a core circuit or at the end of a workout. Prioritize a clean curl and a deliberate heel touch over chasing a high number. ### Is it safe for my lower back and neck? For most healthy trainees, yes, as long as you keep your lower back pressed toward the mat during setup and avoid pulling or straining with your neck. If you feel work shifting into your lumbar area, reduce the range or return to a basic crunch. ### Do I need any equipment for Crunch Heel Touch? No, only enough floor space to lie down fully. An exercise mat makes the position more comfortable on your spine and tailbone, but the movement itself is entirely body weight.
