Here are some exercises on a mat that are nice to do after or before a squat-lunge routine to really isolate the glutes. They can be done with ankle weights for more intensity. I try to use slow and deliberate moves to cut out momentum and place all emphasis on the muscles of my behind.
I will go for high repetitions for each exercises (20-30) doing all the exercises back-to-back as a circuit (for the moves with one leg, on the right side, then on the left side before continuing to the next move), doing the whole circuit 3 times, feeling the burn!
Bridge with weight
Lift your leg straight into the air and lift your hips up.
Bridge with alternating legs
Alternate bridge, leg up 90 degrees, bridge, other leg up 90 degrees.
Bridge swinging leg up and down
Lift your knee, keeping your leg bent at 90 degrees, until your thigh is parallel with the floor. Press your foot up toward the ceiling, then hold for two to three seconds. Slowly lower back to starting position.
Keep your knee bent at 90 degrees, lift your knee out to the side at hip level. Hold for two to three counts at the top of the move. Slowly lower back to the starting position.
Froggy glute lift
Lie on your stomach with arms at your sides, feet together and knees pointing toward opposite walls. Lift your knees 15 cm from the ground, directing your feet toward the ceiling. Hold for two to three counts at the top of the move, then slowly lower to the ground.
Donkey kick lying on the floor
Press your foot up toward the ceiling and hold for two to three seconds, lower back and do it again.
Lift your legs 10 cm from the floor and alternate fluttering your legs up and down as if swimming. Continue for 30 seconds.
