Need help with power in my hips.

First, I'd recommend looking at warmups. I use KB swings in warmups for squats and deads to get my hips firing explosively before I start my working sets.

Swings, romanian deadlifts, reverse hyper, hip thrusts and monster walks will all help build strength.

A simple tweak to swings is to loop a band anchored behind you around the front of the hips. As you swing, you'll have to fire the glutes. You can use this in squat warmups to focus on activation patterns for the glutes/hips too. Just do air or goblet squats with that band position.

Do some cat/camels or whatever they are called to get the feeling of doing that motion. Then just punch through with your hips while you lift and make it an effort to do it with lower weight.

You don't need any special exercises.

All good stuff mentioned so far

Keep your hip flexors stretched out. Having that mobility helps keep a good length-tension relationship for your glutes to be able to work as effectively as possible

Don’t underestimate the use of single leg exercises as that’s gonna put extra work on your glutes. Single leg bridge/hip thrust, step ups truly isolating one leg and not using your opposite leg to propel you up the step, Bulgarian split squats, even easy ones such as the clamshell but you have to make sure you do them right

Also helps to incorporate some sprint work to help open up your hips and that’ll also get you some power too

Try some kneeling one knee hip flexor stretches. Activate those glutes
