If you want to tone, lift, and strengthen your glutes without going to the gym, buying expensive equipment, or following complicated routines, this 21-day butt workouts challenge is exactly what you need!
This progressive program uses five powerful bodyweight exercises that target all three glute muscles: The gluteus maximus (the main muscle that gives your glutes their shape and lift), the gluteus medius and minimus (the side glutes that give your glutes their curves and lift and provide hip stability), and the hamstrings, core, and stabilizers (for complete posterior chain development).
The 5 Butt Workouts in This Challenge
1. Kneeling Leg Lift
Muscles Targeted: Gluteus maximus, hamstrings, lower back stabilizers, core.
How to Do It Step by Step:
- Start on all fours in the quadruped position with your hands under your shoulders and your knees under your hips. Keep your back neutral.
- Engage your core by pulling your navel toward your spine while keeping your spine flat (do not arch or round your back).
- Extend your right leg straight back with your foot flexed (your toes should be pointing down).
- Squeeze your right glute hard and lift your leg upward until it is parallel to the floor or slightly higher.
- Hold for one to two seconds at the top, focusing on glute contraction (imagine pushing the ceiling away).
- Slowly lower your leg with control until your foot hovers just above the floor.
- Complete all reps on the right leg, then switch to the left.
- Reps & Sets: 3–4 sets of 12–20 reps per leg.
Why It Works: This exercise focuses solely on hip extension, which maximizes the activation of the gluteus maximus muscle for enhanced lifting and rounding of the posterior.
2. Lunges
Muscles Targeted: Glutes, quads, hamstrings, core, stabilizers.
How to Do It Step by Step (Forward Lunge):
- Stand tall with your feet hip-width apart, your core engaged, and your chest up.
- Step forward with your right leg, taking a big step of about 2–3 feet.
- Lower your body until both knees bend to about 90 degrees (your front knee should be over your ankle and your back knee should be hovering above the floor).
- Keep your torso upright and don’t lean forward too much.
- Drive through your right heel to push yourself back up to a standing position.
- Squeeze your right glute at the top.
- Alternate legs or do all the reps on one side.
- Reps & Sets: 3–4 sets of 10–15 reps per leg.
Why It Works: This compound move is a triple threat, strengthening the glutes and toning the legs while also giving the metabolism a boost.
3. Fire Hydrant
Muscles Targeted: Gluteus medius/minimus (side glutes), core, hip abductors.
How to Do It Step by Step:
- Start on all fours with your hands under your shoulders and your knees under your hips. Keep your back neutral.
- Engage your core and keep your hips square.
- Lift your right knee out to the side, keeping it bent at 90 degrees and your foot flexed, as if you were a dog at a fire hydrant.
- Raise your knee to hip height or higher and squeeze your outer glute at the top.
- Hold for one to two seconds.
- Lower your knee slowly until it hovers above the floor.
- Complete the reps, then switch legs.
- Reps & Sets: 3–4 sets of 12–20 reps per leg.
Why it works: The glute medius muscle is targeted, and it’s the muscle responsible for rounding the hips, lifting the sides of the butt, and improving stability.
4. Glutes Bridge
Muscles Targeted: Gluteus maximus, hamstrings, core, lower back.
How to Do It Step by Step:
- Lie on your back with your knees bent and your feet flat on the floor, hip-width apart (with your heels 12–18 inches from your buttocks).
- Relax your arms by your sides or across your chest.
- Engage your core and press your lower back into the floor.
- Drive through your heels, squeeze your glutes tightly, and lift your hips toward the ceiling.
- Your body should form a straight line from your knees to your shoulders with no arching.
- Hold for two to three seconds at the top (imagine holding a coin between your glutes).
- Slowly lower yourself back down, keeping your hips just above the floor.
- Reps & Sets: 3–4 sets of 20–30 reps.
Why it works: This foundational glute activator lifts the buttocks, firms the hamstrings, and flattens the lower abdomen.
5. Squat
Muscles Targeted: Glutes, quads, hamstrings, core.
How to Do It Step by Step:
- Stand with your feet shoulder-width apart (or slightly wider) and your toes pointed out 10–30°.
- Engage your core, lift your chest, and look straight ahead.
- Push your hips back first (as if sitting into a chair) and bend your knees.
- Lower yourself until your thighs are parallel to the floor, or as low as your mobility allows.
- Make sure your knees track over your toes and do not cave inward.
- Drive through your heels to stand and squeeze your glutes at the top.
- Reps & Sets: 3–4 sets of 15–25 reps.
Why It Works: This exercise targets large muscle groups. It helps to strengthen the glutes. It also enhances metabolism and defines the legs.
