Sit-up Ball Pass | Friends

Quick Intro

Two partners lie on their backs facing each other, knees bent and the soles of their feet touching. One holds a light medicine ball at the chest. Both sit up together, and at the top the partner with the ball passes it to the other. Both lower back down, then sit up again and pass it back at the top of the next rep. The pass can only happen when both are fully up, which keeps every rep complete.

How to do a sit-up well, curling up from the floor with control and lowering slowly, is taught at Sit-up. This guide covers doing it as a pair: setting the feet, timing the pass at the top and lowering with the ball held safely.

What You’ll Need

A light medicine ball, one to three kilograms.
Two mats placed end to end, or a soft floor.

How It Works

Sit facing each other on the mats, knees bent, and slide toward each other until the soles of your feet touch. Press the soles together lightly. Each partner’s feet help the other’s stay planted.
Lie back. The partner with the ball holds it against the chest.
Both sit up together. One partner counts “up” and “down” for the first few reps.
At the top, the partner with the ball passes it to the other’s chest with a short push.
The receiver catches it and holds it against the chest.
Both lower back down together, slowly.
Sit up again and pass the ball back at the top. Continue for the agreed reps.

Keeping Time Together

Pass at the top only. Wait until both are fully upright. The pass is a built-in check that both finished the rep.

Short, soft passes. At the top you are close together. A small push from the chest is enough.

Hug the ball on the way down. Hold it against the chest with both arms. Lowering with the ball held out in front pulls on the lower back and makes the head drop faster.

Lower slowly. A controlled descent is half the work of a sit-up. Count two or three seconds on the way down.

How Many

Sets of 10 to 20 sit-ups, one pass per rep. Rest a minute between sets. Two or three sets is a good core block.

Making It Easier or Harder

Easier: no ball at first, or a lighter one. You can also pass only every other rep.
Harder: a slightly heavier ball, a slower descent or a short pause at the top before each pass.

Staying Safe

Use a light medicine ball.
Keep the pass controlled at the top, never rushed.
Hold the ball to the chest while lowering.
Stop for neck or lower back pain. Pulling on the neck to sit up means you need an easier version.

Common Mistakes

Passing on the way up. Wait until both are at the top.
Feet sliding apart. Keep the soles pressed together.
Flopping back down. Lower slowly.
Pulling with the head. Lead with the chest and keep the chin slightly tucked.

Partners of Different Sizes

A taller partner’s knees sit higher, and their chest arrives a little further forward at the top. That is fine. Slide closer or further apart until the soles meet with both knees comfortably bent, then check that the pass travels a short distance for both. If one partner’s feet keep lifting as they sit up, the other presses the soles a touch more firmly to help hold them down.

Fitting It Into a Session

Sit-up passes make a steady core finisher once the heavier work is done. They need only a ball and mats, so it suits sessions at home or in a park.

Sit-up is the solo version.
Medicine Ball Squat Pass passes at the bottom of a squat.
Partner Sit-up with Feet Hold has a partner anchor the feet.
Core Rep Battle turns core exercises into a contest.

FAQ

Do we need to touch feet?

Pressing the soles together keeps both partners’ feet from sliding and sets the distance for the pass. Without it, the feet tend to lift.

What if one of us cannot sit up all the way?

Go without the ball until full sit-ups are comfortable, or try the version with a partner holding the feet.

How heavy should the ball be?

Light. One or two kilograms is plenty for most people, since you hold it through the whole descent.

Should we cross our arms when we do not have the ball?

Arms crossed over the chest or held forward both work. Keep the hands off the back of the head, which tempts you to pull on the neck.
