Correctly balancing the glutes and legs requires knowledge of where you are weak and tight. If you can correctly identify this, then focus on strengthening the weak areas and stretching the tight areas.
P.volve focuses on increasing mobility in the hips, so this can help with balancing the body. It is common to have one side slightly weaker or tighter than the other, as our daily movement patterns can be habitual and feed into these imbalances.
Be mindful of changing up your movements to create more variety and balance from right to left.
