Place a foam roll at the top of the right leg just below the right glute (butt cheek). Place your hands at your sides and lean to the right and back. This will lift the left glue off the foam roller, placing more compression on the right glute.
Slowly roll up the right glute to just below the back of the right hip bone. Stop and hold for 20-30 seconds on any knots or tight spots.
Repeat on left glute.
