Hip stability or more accurately lack or hip stability could be the reason your hips always feel tight. If we lack stability our bodies naturally compensate and make up of that lack stability with increased passive muscle activity to support our joints. Try these simple exercises to gain hip stability and get more out of your workouts.
There are more progressions but I like these 3 because they are all different stress to the muscles. With the KB and standing band we are actively using our hip flexors and getting stance stability on the opposite side. The band exercise on the back helps gives you an active isometric contraction.
Consistently is key to results, perform 1-2 of these exercises 2-3 days a week for 8-12 reps adding weight or resistance as needed. You should follow these exercises up with some banded hip extension or couch stretch to get the most from the stability exercises.
