The medicine ball sit-up (wall) is a weighted sit-up that targets the hip flexors (iliopsoas) and abs (rectus abdominis), with the obliques, quadriceps, adductors, pectineus, and sartorius assisting at the hips and the posterior deltoid and teres major holding the ball in place. Pressing your feet into a wall anchors your lower body without a partner or a foot pad, so you can load full-range sit-ups and build core strength and endurance.

Cómo hacer el Medicine Ball Sit up (wall)

  1. 1Sit on the floor about 30–60 cm (1–2 ft) from a wall and plant both feet flat against it, knees bent to roughly 90 degrees and hip-width apart.
  2. 2Hold the medicine ball with both hands against your chest, elbows pointing down toward the floor.
  3. 3Brace your core and press both feet evenly into the wall to anchor your lower body.
  4. 4Lie back under control until your upper back and head rest on the floor, keeping the ball at your chest.
  5. 5Curl your torso up by drawing your ribcage toward your hips, leading with your chest rather than your chin.
  6. 6Keep curling until your lower back has fully left the floor and your torso is upright over your hips.
  7. 7Pause briefly at the top, then reverse the movement and lower your torso to the floor at the same controlled speed.
  8. 8Repeat for the target number of reps without letting your feet lose contact with the wall.

Consejos de técnica

  • Exhale as you curl up and inhale as you lower, keeping your core braced throughout so intra-abdominal pressure supports your spine under the added load.
  • Press the whole foot — heel and forefoot — evenly into the wall on every rep; even pressure keeps your hips planted and stops your feet from creeping upward as you fatigue.
  • Keep your eyes on the ball rather than the ceiling; that alone holds your chin tucked and your neck in line with your spine.
  • To progress without a heavier ball, hold it at your forehead or with your arms extended overhead — the longer lever increases the demand on your abs at the same load.
  • Choose a ball weight that lets you complete every rep at a smooth, controlled tempo; if form breaks down before the last rep, drop the load.

Errores comunes

  • Jerking the head and neck forward to start the rep, which strains the cervical spine and shifts work away from the abs.
  • Swinging the ball upward for momentum, which turns a controlled contraction into a ballistic throw and unloads the abs at the hardest part of the range.
  • Letting the lower back arch off the floor at the bottom instead of holding a neutral spine, which releases tension on the rectus abdominis and loads the lumbar spine.
  • Sitting too far from the wall so the legs are nearly straight, which cuts the hip flexors' leverage and makes the feet slide instead of anchoring.
  • Dropping back to the floor at the end of each rep, which throws away the eccentric stimulus and jars the spine under the extra weight.

Preguntas frecuentes

What muscles does the medicine ball sit-up (wall) work?

The target muscles are the hip flexors (iliopsoas) and the abs (rectus abdominis). The obliques, quadriceps, adductor brevis, adductor longus, pectineus, and sartorius assist at the hips and trunk, while the posterior deltoid and teres major hold the medicine ball against your chest.

How heavy should the medicine ball be and how many reps should I do?

Start with a ball you can control for 10–15 reps with no loss of form — often 4–6 kg for beginners — and do 3–4 sets. Move up in weight only once you can keep a smooth tempo through every rep, including the lowering phase.

What is the difference between this and a regular sit-up?

The wall anchors your feet without a partner or a pad hooked under your heels, so the setup stays consistent rep to rep. The medicine ball adds resistance a bodyweight sit-up does not have, making each rep harder and bringing the posterior deltoid and teres major in to stabilize the load.

How far should my feet be from the wall?

Set up so your knees sit at roughly 90 degrees with your feet flat on the wall — about 30–60 cm (1–2 ft) for most lifters. That angle gives the hip flexors good leverage and lets you press firmly into the wall without your hips lifting off the floor.

Can I do this exercise if I have lower back pain?

Sit-ups involve repeated loaded lumbar flexion, which can aggravate some disc and facet conditions, so check with a healthcare provider before adding this one if you have existing back issues. Lifters cleared to train usually do best keeping the tempo controlled and avoiding lower-back extension at the bottom.
