Stability ball hip extension leg curl

This is one of the best workouts to get your glutes nice and strong. Start off by laying on the floor face up with your arms out to the sides. Then lower your legs onto a stability ball, pushing your hips up until you’ve formed a straight line with your body. Now pull your heels towards you and roll the ball close to your butt as much as you can and then pause. Roll the ball back and form your body into a straight line again and repeat for 6 reps.
The kickback

I actually love doing this move because it’s so easy, yet so affective. Simply get on all four and then kick your right leg straight behind you at a 45 degree angle for about 90 seconds. Repeat with the left leg and do this 5 more times.
Dumbbell Bent-Knee Dead Lift

Grab a set of dumbbell weights and set them on the floor right in front of you. Now squat down and grab them with an overhand grip. Make sure that your arms are straight and your back is slightly arched, then squeeze your glutes and push yourself up with the dumbbells. Repeat for 5 reps.
Kettlebell swings

Think squats but 10 times more intense. Begin by holding a light kettlebell with both your hands, making sure to keep your feet hip width apart. Now swing the bell towards the back of your body and make sure to push your hips and thighs forward while you swing your arms in front. Every time you bring back the kettle towards the ground, squat down.
Reverse lunge

Begin by standing tall with dumbbells in each hand, then take a large step backwards with your right foot and lower your right leg until it’s only a few inches away from the ground. Now lower your body until your left knee is bent at a 90 degree angle. Use your muscles to bring your right foot back to starting position and then repeat with your left foot. Repeat for 10 more reps.
