I'm actually not sure what the exercises themselves are called, so I apologize beforehand if this is a little awkward.
I use some resistance bands for this purpose. They're fairly cheap on Amazon and work fairly well. The exercises are as follows
- Lay on side with band near the knees on upper leg. Upper leg at 45 degree angle with waist, lower leg at 90 degree angle with upper. I then separate my legs. I do both legs
- I stand up with band in same place. I then kick laterally as far as I comfortably can. I do both legs as well though I'm careful with my left one due to injuries.
- I then get on all fours with the band, again, in the same place. I kick outward with one leg and return it. I do both legs here
- In same position, I instead kick backward and straighten the leg. Both legs once more
I do about 20 reps each leg on each exercise with the heaviest band, so that may be why the progress is so fast. I couple them with my physical therapy exercises that I have to do for surgery. I do 2 days on, 1 day off so the muscle can recover.
Also, if anybody who knows better than I can suggest more exercises, please do. I want to have hips.
Oh, I also am starting up a regimen with my Total Gym here soon with a ton of exercises with that. Just gotta find space to set it up again. Has a ton of leg, hips, and ass exercises that I want to take advantage of as well. My set even came with a workout routine in the box perfect for this purpose. So hopefully that does even more.
