What Happens When You Do Butt Clenches in Your Seat?

A strong and fit posterior not only looks good, but it also assists in many of the movements you make throughout the day, such as standing, bending, walking upstairs. Therefore, getting in some butt exercises while you're stuck in a seat at work or just watching TV may hold a lot of appeal.

Enter butt clenching. The action of tightening, then releasing, your glutes — that is, butt clenches — may help strengthen the muscles, but it won't give you the firmness or shape an exercise the way lunges or squats will.

The strengthening benefits of routine butt clenching may well be worth the effort, however. If your glutes are weak, your body might try to compensate by using other muscles during these actions, which could lead to problems such as back, hip or knee pain— and no one wants that.


Butt clenching can increase the strength of your glutes, without even requiring you to get out of your chair.

All About Those Glutes

The butt muscles — also called gluteal muscles or glutes — include the gluteus maximus, gluteus medius and gluteus minimus. The gluteus maximus forms the bulk of the buttock region. You can locate the gluteus maximus by placing a hand on each of your butt cheeks.

This muscle acts as a powerful extensor of the hip and participates in lateral rotation and abduction, such as when you kick your leg out to the side or rotate and extend your leg behind you. The gluteus medius and minimus muscles are layered beneath the gluteus maximus.

In addition to assisting in hip motions, these smaller muscles are also important postural muscles, keeping your pelvis level as you walk. When you do butt clenches in your seat, you are primarily activating the gluteus maximus, a worthwhile muscle to target. When it is weak, the muscles along the lower spine, as well as the hamstrings, will often overcompensate. That can result in back tension and spinal misalignment.

Performing the Butt Clenching Exercise

The movement of butt clenching is quite small — essentially, it's shrinking the size of your buttocks inward from the sides. While sitting in your seat, tense and squeeze your butt, aiming to raise yourself slightly while remaining seated. The slight lift should be the result of the tensed gluteal muscles and not of leaning forward or pressing down on your feet.

Do not inadvertently tense your thigh muscles or hamstrings. Keep your legs relaxed, and tense only your butt. Hold the clench for five seconds, then relax the muscles for five seconds. Each squeeze and release is considered one repetition. Perform two sets of 30 repetitions each day. As muscle strength improves, increase the length of time you hold each clench, aiming for 10 seconds or more.

More Effective Glute Exercises

When the American Council on Exercise asked ACE-certified personal trainers what exercise provided the fastest route to strong and developed glutes, the overwhelming consensus was squats. This answer, though, was merely opinion. So, ACE funded a study to conclusively determine exactly which exercise is most effective at toning the glutes.

During the investigation, subjects performed a variety of gluteal exercises as the researchers compared activity in three different muscles: the gluteus maximus, the gluteus medius and the hamstrings. The results showed that the traditional squat is, in fact, especially effective, but so too are five additional exercises: single-leg squats, quadruped hip extensions, step-ups, lunges and four-way hip extensions.
