Why a Sit-Up Mat Changes the Movement

On a flat floor, a sit-up stops when your back touches down. Your abs do not reach the lengthened position at the bottom of the rep, and your tailbone takes direct contact every time you lower. For many people, the set does not end because their abs are done. It ends because the floor starts to hurt.

A contoured mat changes both of those things. The curve lets your spine settle slightly past neutral, so your abs lengthen fully before they contract. The cushioning also takes the floor out of the equation, so the set can end when your muscles are done, not when your tailbone is.

The Tailbone Protector Pad

Most ab mats end at the curve. Your lower back gets support, but your tailbone hangs off the back onto the bare floor, and high-rep sets find that spot fast.

The Athlos Ab Mat extends a flat, cushioned pad out from the back of the curve. Your tailbone rests on the pad through the entire movement. The pad is attached, so it never shifts out of place mid-set. Multiple reviewers say the pad is what let them do sit-ups again after years of avoiding them.

What the Best Ab Mat Gets Right

Three things decide whether a mat holds up: foam density, shape, and grip.

The foam here is dense enough to keep its shape through years of daily use. It does not bottom out under body weight, and the shape stays consistent whether you are on rep 5 or rep 500. The contour matches the natural curve of your lower back, so the support lands where the movement needs it. The non-slip base keeps the mat in place during fast, high-rep sets.

We have made this one product since 2014, refining it with feedback from thousands of verified buyers. It handles sit-ups, butterfly sit-ups, and back extensions, and it works as cushioning for any floor movement where your lower back or tailbone meets the ground.

★★★★★ Tailbone Comfort

"Both my wife and I now use it and it makes a world of difference on tailbone pain and how easy it is to do situps without undo back strain. No more straining/hurting our backs and we are getting more and more situps done. This is no gimmick, it works and well."

★★★★★ Beats Everything Else

"I bought this after trying Nike's $50 thick yoga mats, mini yoga pads, and even cut up my own block of memory foam for coccyx support and this Athlos product beat ALL of them. The elevation provides great comfort and might even be giving you a nicer workout."

Frequently Asked Questions

A mat that earns that label does two jobs: it supports your lower back through a full range of motion, and it protects your tailbone at the bottom of every rep. Most mats handle the first job and stop at the curve. The Athlos mat also handles the second with an attached tailbone protector pad, and its foam is dense enough to hold its shape for years of daily use. That combination is what 1,836 Amazon reviewers have rated 4.5 stars.
It is a contoured foam pad, also called an ab mat, that sits under your lower back during sit-ups. You can absolutely do sit-ups without one. But the flat floor cuts off the bottom of the movement and puts direct pressure on your tailbone, and the mat solves both of those problems at once.
Two ways: directly on this page through Stripe checkout, or on Amazon. The price is $33.99 either way, both orders ship through Amazon's fulfillment network, and every purchase includes the free 28-Day Core Strength Blueprint.
Curved side up, flat side on the floor. Lower your back onto the mat so the highest point of the curve sits under your lower back and your tailbone rests on the tailbone protector pad. Our setup and technique guide walks through positioning, form, and common setup mistakes.
