Partner Foot-Lock V-up | Friends

Quick Intro

Partner Foot-Lock V-up uses a partner anchor to help with the V-up, a demanding core exercise where the upper body and the legs rise together and the hands reach toward the feet. The working partner lies flat. The anchoring partner kneels at their feet with both hands locking the ankles. The working partner lifts the trunk and legs into a V, lowers back down under control and repeats. When the agreed reps are done, the anchor takes a turn as the worker.

The V-up itself is covered at V-up. This guide covers what the anchor adds and how the anchoring partner holds without getting in the way.

What You’ll Need

A mat or soft floor.
Room for the anchoring partner to kneel at the working partner’s feet.

How It Works

The working partner lies flat on their back, legs straight, arms reaching overhead along the floor.
The anchoring partner kneels facing them, at their feet, and wraps both hands firmly around the ankles.
The working partner raises the arms, trunk and legs together, reaching the hands toward the feet at the top.
As the legs rise, the anchoring partner keeps the hands around the ankles and lets them lift, keeping the two legs together, and the working partner reaches toward the anchor’s hands.
The working partner lowers the trunk and legs back to the floor under control.
On the way down, the anchoring partner lets the heels settle softly to the floor, so they never drop, and steadies the feet there for a moment before the next rep.
After the agreed number, the two swap.

For the Anchoring Partner

Soft at the bottom. Let the heels come down gently and steady the feet for a moment between reps, so each rep starts from still. Do not press them into the floor, since the legs need to leave it at the same moment as the trunk.

Follow, do not fight. As the legs come up, let them rise with your hands. Holding them pinned to the floor would turn the V-up into a sit-up.

Never lift or pull. The working partner raises their own legs. Your hands go with them; they do not do the lifting.

Watch for swinging. If the working partner starts throwing the arms to get up, tell them to slow down.

Anchoring in general, including how firm to hold, is covered in Stretching, Resisting and Anchoring a Partner.

What the Partner Changes

The hold does not lift the legs or give the working partner anything to pull against, as the held feet in a partner sit-up do, since in a V-up the legs leave the floor too. Every part of the lift is the working partner’s own effort. What the partner adds is control. The hands keep the two legs together and level as they rise, which stops one leg leading or the legs drifting apart. The anchor’s hands also give a clear target to reach for at the top, so each rep finishes at the same height. On the way down, the anchor stops the heels dropping onto the floor, which keeps the lowering slow and spares the heels.

How Many

Start with 6 to 10 controlled reps and swap. Two or three sets each is enough.

Making It Easier or Harder

Easier: a bent-knee tuck-up, with the knees drawn toward the chest and the hands reaching past the shins. The anchoring partner holds the ankles in the same way.
Harder: a slower lowering, or a one-second pause at the top of the V.

Staying Safe

Keep it controlled. Swinging up with the arms is the common shortcut. Rise and lower with control.
Watch the lower back. Stop if it rounds a lot at the top or hurts on the way down.
Clear space around the head and arms.

Common Mistakes

Anchor pinning the legs. The legs must be free to rise.
Dropping back to the floor. Lower slowly, or the lower back and head hit the floor hard.
Bent arms. Reach long through the arms toward the feet.
Holding the breath. Breathe out on the way up.

Getting Better Over Time

Move from the tuck-up to the full V-up once ten tuck-ups feel smooth. On the full V-up, the next step is a slower lowering, and later trying a few reps without the anchor.

Fitting It Into a Session

Use it in a core block with planks or back extensions. It is harder than most core exercises, so put it before the easier ones.

Tuck V-up is the bent-knee version.
Partner Sit-up with Feet Hold uses the same kind of anchor for a classic sit-up.
Partner-Held Back Extension works the back of the trunk with a partner holding the ankles.

FAQ

Why does the anchor help with a V-up?

It keeps your legs together as they rise, gives your hands a target at the top and keeps the lowering slow. The lift itself is still all yours.

Should my partner keep my feet on the floor?

Only lightly, between reps. As you rise, the legs come up and the hands go with them.

How do I stop swinging?

Slow down, use the tuck-up for a while and breathe out as you rise.
