This exercise mainly works the muscles on the sides of your waist (obliques).

Stronger obliques help you have a more toned midsection.

This exercise also improves your balance and posture because it strengthens the muscles that support your spine.

It's suitable for people of all fitness levels, from beginners to advanced exercisers.

Doing this exercise regularly can make your core stronger and improve how well you do in sports or other physical activities.

To do the exercise, lie on your back with your knees bent and feet flat on the floor. Then, bring one knee towards your chest while simultaneously lifting the opposite leg straight up. As you do this, twist your torso towards your bent knee. Slowly lower your leg and return to the starting position. Repeat on the other side.

Remember to focus on controlled movements and proper form to avoid injury. If you are unsure about the correct technique, consult a fitness professional.

This exercise works your obliques, the muscles on the sides of your waist. Stronger obliques mean a stronger core overall.

Improved core strength leads to better balance. You'll feel steadier on your feet and less likely to wobble.

This exercise can help tone your waistline, giving you a more defined midsection. It's a good way to improve your body shape.

A strong core helps you stand and sit up straighter. Good posture is important for preventing backaches.

This exercise is easy to adapt for different fitness levels. Beginners can do fewer repetitions, while more experienced people can add weights or do more reps.

Oblique crunches are a good choice for anyone wanting to improve their core strength and overall fitness. They're a simple yet effective exercise.

This is your starting position. Make sure your legs are straight and your lower back is flat on the floor.

Tighten your tummy muscles.

Imagine you're trying to pull your belly button towards your spine. This helps protect your back and makes the exercise work better.

Lift your shoulders off the floor while breathing out.

Try to reach your feet with your hands. Don't pull on your neck; use your tummy muscles to lift.

At the same time, lower your legs a little.

Keep your legs straight and just lower them a few inches above the ground. Don't let them touch the floor.

Slowly bring your shoulders and legs back to the starting position.

Control the movement as you go back up and down. Don't rush.

Do this 10 to 15 times.

Rest when you need to before doing more.

Remember to use your tummy muscles, not your neck, to lift your shoulders.

Captain's Chair Straight Leg Raises: This exercise uses a special chair to help you lift your legs straight up. It's good for your lower stomach muscles and the muscles that help you bend at your hips. The chair keeps you steady, making it easier to focus on the muscles you're working.

Twisted Leg Raises: Lie on your back and lift your legs. As you lift, twist your legs to one side, then the other. This works your lower stomach muscles and your obliques (the muscles on the sides of your waist). You don't need any equipment for this one – perfect for home workouts!

Reverse Crunches: Lie on your back and bring your knees towards your chest, lifting your hips off the ground. This exercise focuses on your lower abdominal muscles. It's a gentle way to strengthen your core without putting too much strain on your neck or back.

Each of these exercises is different, so you can mix them up to keep your workouts interesting and effective. Find what you like best and stick with it!

Oblique Crunches: Lie on your back, knees bent. Lift one shoulder towards the opposite knee, keeping your lower back flat on the ground. This works the side muscles of your stomach.

Straight Leg Oblique Crunch: Similar to above, but keep your legs straight out. This is harder and works your core even more.

Otis Ups (or Bicycle Crunches): Lie on your back. Bring one knee towards your chest while extending the opposite arm. Switch sides, like riding a bicycle. This is great for your whole core.

Regular Crunches (with a twist): The basic crunch is a good starting point. To make it harder and work your obliques, twist your body slightly as you crunch up.

Why these are good: Each exercise works your core muscles in a slightly different way. This helps you build a stronger, more balanced core. It also makes your workouts more interesting!

Control your movements: Don't rush! Slowly bring your elbow towards your opposite knee, then slowly return to the starting position. This helps you feel your muscles working and prevents injury.

Keep your legs straight and up: Lift your legs straight up, keeping them a few inches off the ground. Avoid arching your back. If your lower back hurts, lower your legs slightly.

Keep your stomach muscles tight: Imagine pulling your belly button towards your spine throughout the exercise. This helps protect your back and makes the exercise more effective.

This exercise strengthens your core muscles, making your tummy and back stronger.

Doing it right is key. Let's learn how:

* Lie on your back with your knees bent and feet flat on the floor. Your hands can be behind your head or crossed on your chest.

* Slowly lift one leg straight up while twisting your upper body towards the opposite side. Try to touch your opposite elbow to your knee.

* Slowly lower your leg and upper body back to the starting position.

* Repeat on the other side. That's one rep.

Benefits of this exercise include a stronger core, better balance, and improved posture.

Common mistakes to avoid:

* Don't pull on your neck. Keep your neck relaxed and your chin slightly lifted.

* Don't swing your legs. Use controlled movements.

* Don't arch your back. Keep it flat on the floor as much as possible.
