It works your glutes (butt muscles), hamstrings (back of your thighs), and upper back.

It also makes your core (stomach muscles) stronger.

This exercise helps you become more flexible and improves your balance.

It strengthens the back of your body, which is important for good posture and movement.

It's a good exercise for everyone, whether you're a beginner or an experienced Pilates person.

Doing this exercise well helps you move better and understand how your body works.

To do the exercise, lie on your back with your knees bent and feet flat on the floor.

Slowly lift one leg at a time, keeping your core engaged and your back flat on the floor.

Lower your legs slowly and repeat. Focus on controlled movements.

It strengthens your glutes and hamstrings. These muscles are in your bottom and back of your thighs. Strong glutes and hamstrings help you jump higher and run faster.

It helps you stand up straighter. The exercise works your upper back muscles, which improves your posture and helps prevent back pain.

It makes your core stronger. Your core muscles are in your stomach and back. A strong core helps with balance and makes it easier to do other exercises.

It improves your hip and shoulder flexibility. This means you can move your hips and shoulders more easily and comfortably.

It helps you pay attention to your body. You learn to control your movements better, which improves coordination and balance.

Tighten your tummy muscles by pulling your belly button in towards your spine. This helps protect your back and makes the exercise more effective.

Bend your knees and bring your heels up towards your bottom. At the same time, lift your chest off the mat just a little bit.

Grab your ankles with your hands. Keep a firm grip but don't pull too hard.

Kick your legs back twice, pushing against your hands. Try to keep your chest and hips still. This is the main part of the exercise.

Slowly lower your legs and chest back to the starting position. Control the movement to avoid injury.

Repeat the kicks as many times as you want to do. Remember to listen to your body and rest if you need to.

Important tip: Focus on keeping your upper body still while you kick your legs. The less your chest and hips move, the better you'll work your leg and core muscles.

Want to change things up? Here are some similar exercises that give you similar benefits but with a little different focus:

Lying Leg Raise and Hold: This exercise is all about your lower stomach muscles and making your core stronger. Instead of moving your legs up and down like in the Double Leg Kick, you hold them up. This helps you build core endurance (how long you can hold a position).

Flutter Kicks: This one works your core and the muscles in your hips. You move your legs up and down quickly and smoothly. It's more about building endurance and stability than just strength.

Lying Leg Raises: This is like the 'Lying Leg Raise and Hold' but you lift and lower your legs. This helps build strength and flexibility in your hip muscles, and it's a good addition to the Double Leg Kick.

All these exercises work similar muscles but in slightly different ways. Try them all and see which ones you like best to reach your fitness goals!

Lying Crunch with Leg Lifts: This exercise is like doing a crunch while also lifting your legs. It makes your stomach muscles stronger and also helps your hips and legs become more flexible. This is good for overall balance and stability.

Side Lying Leg Lifts: Lie on your side and lift your top leg. This exercise focuses on your buttock muscles and the outside of your thighs. It helps you get stronger in your hips and improves how well your hips move. It's great for shaping your legs.

Lying Hip Circles: Lie on your back and move your legs in circles. This works the muscles in your hips and stomach. It helps make your hips more flexible and stronger, which is important for many activities.

These exercises all work similar muscles to the lying double leg kick, but they move your body in different ways. Try them out and find what you like best!

Don't kick too hard: Gentle, controlled movements are better than powerful kicks. Focus on the feeling of the stretch, not how high your legs go.

Keep your shoulders relaxed: Your upper body should stay still and calm. Avoid tension in your neck and shoulders. Try to keep your shoulders flat on the ground.

Use your core muscles: Your stomach muscles should be working to help you lift your legs. This keeps your back safe and helps you control the movement.

This exercise focuses on your posterior chain – that's the group of muscles along the back of your body, from your calves to your back.

Good form is really important to get the most out of this exercise and to avoid injuries. Focus on slow, controlled movements.

Start by lying on your stomach. Keep your legs straight and together, and slowly lift them off the floor a little.

Then, lower them back down slowly. Repeat this movement several times. Try to feel the muscles working in your hamstrings (back of your thighs), glutes (buttocks), and lower back.

As you get stronger, you can try lifting your legs higher and holding them for a few seconds before lowering them.

This exercise is a fantastic addition to your Pilates routine, helping to improve strength, flexibility, and body awareness.

Remember to listen to your body. If you feel any pain, stop and rest. It's better to start slowly and gradually increase the difficulty as you get stronger.
