What is the #1 best glute exercise?

Step-ups are the ultimate all-in-one move. They can light up your glutes, sometimes even pushing past 100% activation.

At what age do buttocks stop growing?

Your bone structure is largely set once your pelvis fully fuses in your early 20s. That part doesn’t change. But muscle growth is a lifelong game. The 2025 MRI research shows that while aging and too much sitting can lead to muscle thinning, consistent resistance training can fight that off and build glute volume at any age.

What machine targets the side glutes?

The Cable Machine (used for standing abductions) and the Seated Abduction Machine are your best bets. These allow you to apply the mechanical tension for actual muscle growth.

Are squats better than lunges?

When it comes to the side booty, lunges and Step-Ups take the spotlight. Squats can build overall glute mass, but lunges target each leg individually. This can make the gluteus medius fire up to keep your hips stable.

Is it OK to train side glutes every day?

Absolutely not. As we saw in the growth timeline, your muscles need 48 to 72 hours to recover and build through protein synthesis. Hitting them every day skips the crucial rest phase, which can prevent you from seeing results within the 8-12 week hypertrophy window.
