In February, I shared a glute pic on the 'gram, explaining that I've been incorporating new-to-me movements in order to build strength and develop definition in my glutes. I got an overwhelming response from the community, and so I'm going to put together a whole post on what I've learned and what movements I've been incorporating very soon.
Until then, the hip thrust movement you see here is one such exercise. It's easy to do pretty much anywhere, whether you're traveling, at home, or at a gym, and it's really effective (especially if your glute strength is lacking - that's the benefit of being a beginner, you really make gains quickly). The quick demo is below - I hope it's helpful! You'll need an ottoman or something of similar height. Then, you'll position your upper back against the edge of it, and step your feet about halfway away from your body. From there, push into the heels in order to lift the hips Give it a shot and let me know how it goes for you down in the comments section below.
