The side of your bum is primarily the gluteus medius muscle (part of your "side butt"), crucial for hip stability and movement, located on the outer upper buttock, while the fold underneath is the gluteal sulcus, a horizontal crease between the buttocks and thigh. The entire area is the gluteal region, containing the gluteus maximus, medius, and minimus muscles.
Piriformis syndrome occurs when your piriformis muscle compresses your sciatic nerve and results in inflammation. It can cause pain or numbness in your buttock and down the back of your leg. It can happen on one side of your body or both. The piriformis is a flat, narrow muscle.
anus. The opening of the rectum to the outside of the body.
The intergluteal cleft is a surface anatomy landmark of the pelvis and lower limb. It is the deep furrow or groove that lies between the two gluteal regions (commonly known as the buttocks). It extends from sacral level S3 or S4 and ends just inferior to the apex of the sacrum, at the level of the anus.
Below you can find some of the best side booty exercises to target the side of your hips and get well-rounded glutes.
The gluteus medius is located on the lateral aspect of the upper buttock, below the iliac crest. The superior part of the muscle is broad, narrowing towards its insertional tendon, giving it a fan-shaped appearance.
Can a saggy butt be fixed with exercise? Yes, targeted exercises such as squats, lunges, and hip thrusts can strengthen and lift the gluteal muscles, improving firmness and contour. However, exercise alone may not fully correct significant sagging or skin laxity.
Side glutes are stabilizer muscles. Because of this, side glute exercises where you work out one leg at a time can really help activate those side glutes. The single leg hip thrust is one of the best side glute exercises that uses this unilateral (single leg) style.
The terms plumber butt or plumber's crack (Canadian, Australian, and American English) and builder's bum (English) refer to the exposure of the buttock cleavage. The expression "builder's bum" was first recorded in 1988.
Sexologists have been using the term hypersexuality since the late 1800s, when Krafft-Ebing described several cases of extreme sexual behaviours in his seminal 1886 book, Psychopathia Sexualis.
Slang for "bum" (buttocks) includes common terms like butt, ass, bottom, backside, tush, and buns, along with regional or more informal words like arse (UK), fanny (US), keister (US), booty, and caboose, and even funnier ones like gluteus maximus or the moon, depending on context and region.
(vulgar slang) A buttock.
Red flags for buttock pain needing urgent care include loss of bowel/bladder control, severe leg weakness, saddle numbness (groin/inner thigh numbness), fever/chills with pain, severe night pain disrupting sleep, or pain after trauma, suggesting serious issues like cauda equina syndrome or infection, while persistent, worsening pain, or numbness/tingling warrant a doctor's visit to rule out sciatica, disc issues, or SI joint problems.
However, vitamin deficiencies in B12, D, and magnesium play a key role in sciatic pain and relief. If you've tried stretches, painkillers, or even therapy and found little to no relief, this could be your answer. A B12 vitamin deficiency, for example, leads to increased nerve pain and sciatica symptoms.
Sciatica pain can make it difficult to fall asleep and to remain so because lying down can put pressure on your lower spine, causing significant pain. This is especially true if you are sleeping in certain positions, such as on your stomach.
The gluteus medius is a broad, thick, radiating muscle, situated on the outer surface of the pelvis. It lies profound to the gluteus maximus and its posterior third is covered by the gluteus maximus, its anterior two-thirds by the gluteal aponeurosis, which separates it from the superficial fascia and skin.
The 8-8-8 glute method is a high-intensity technique for hip thrusts, involving 8 full reps, followed by 8 partial (pulse) reps, and finishing with an 8-second isometric hold at the top, creating intense muscle fatigue and pump for glute growth. While great for mind-muscle connection and targeting the top contraction, some experts suggest traditional sets might be better for progressive overload and strength gains, making the 8-8-8 method a good finisher or variation rather than a primary routine.
A strong backside for good reason
The amazing muscles in your backside – known as your gluteal muscles – help your body stay upright, keep your body moving forward and help you power through your workouts. Keeping your posterior healthy can make a big difference in your every move.

The shape of the buttocks is defined by muscles known as the glutes. That's the gluteus maximus, gluteus medius, and gluteus minimus, as well as the fat that lies over them. Walking, running, and climbing all work the glutes. Strength training that targets these muscles can help give you a tighter, more rounded look.
Aging is an inevitable process, but it often feels like it sneaks up on us. Many people first notice visible skin sagging around age 35, even if they've maintained a solid skincare routine. The culprit? A combination of natural biological changes, environmental stressors, and lifestyle factors.
Will doing squats every day make my bum bigger? Squats can help shape and build your glutes, but growth requires a combination of proper form, resistance, recovery, and consistency. Doing squats every day may lead to fatigue or plateau—aim for 2–3 focused sessions per week for best results.
