It works many muscles: your obliques (side muscles), hip flexors (muscles in your hips), and quadriceps (front thigh muscles).

This makes it useful for all fitness levels, from beginners to advanced exercisers.

It's easy to add to your workouts, whether you're building strength or recovering from an injury.

A stronger core helps you stand up straighter and keeps your body steady.

This improves how well you do things that need balance and strength.

Improves balance: Doing this exercise helps you stand steadier and prevents falls, especially important as you get older.

Increases flexibility: It stretches your hip muscles and lower back, making you more bendy and less likely to get stiff.

Gentle on your joints: It's a low-impact exercise, meaning it's easy on your knees, hips, and ankles, making it suitable for many people.

Easy to adapt: You can change how hard it is, making it perfect for beginners or advanced exercisers. You can also do it anywhere – at home or the gym.

This is important for safety and to make sure you do the exercise correctly. Your feet should be placed comfortably apart, shoulder-width apart is usually a good starting point.

Lean back a little. Keep your tummy muscles tight. This helps you stay balanced and protects your back.

Slowly stretch your legs out in front of you. Imagine a diagonal line from your hips to your feet. Don't point your toes straight forward, angle them slightly outwards.

Gently bring your knees back towards your chest. Keep your feet at that diagonal angle. Don't let your knees collapse inwards.

Slowly stretch your legs back out to the starting position. Control the movement. Don't just let your legs flop.

Do this as many times as you're supposed to. Listen to your body. If you feel any pain, stop.

Remember to keep your balance. Use your core muscles (your tummy and back muscles) to help you stay steady. This is a key to doing the exercise properly and safely.

If you're new to this exercise, start with a smaller number of repetitions. As you get stronger, you can do more.

This exercise helps strengthen your legs and core. It improves your balance too!

This exercise is great for building strong core muscles and better balance.

Want to try something different? Here are some variations:

Diagonal Reach on Chair: Sit on a chair and reach one arm across your body towards the opposite knee. This works your side muscles (obliques) and shoulders, making you more flexible and steady.

Leg Raises on Chair: Sit tall on a chair and lift your legs one at a time. This focuses on your lower stomach muscles and helps your hips move more easily.

All these exercises help make your core stronger and more stable.

They all work similar muscles, but in slightly different ways.

Changing up your exercises helps you avoid getting stuck in a rut and keeps your workouts interesting.

Try all three exercises to find your favorites and build a well-rounded core workout!

Diagonal Reach on Chair: This exercise helps you get stronger and more flexible in your core, shoulders, and lower back. Instead of moving in and out, you reach out to the side, improving your range of motion and how well you can coordinate your movements.

Leg Raises on Chair: This focuses on your lower stomach muscles and hip muscles. Lifting your legs while sitting strengthens your core in a different way than the Diagonal In-Out, building strength and balance.

One-Legged Diagonal Kick with Exercise Ball: This exercise works your hamstring and buttock muscles, and also uses your core for balance. Using an exercise ball makes it harder, challenging your coordination and strength.

These exercises all work similar muscles, but in different ways. They'll keep your workouts interesting and help you stay fit!

Move slowly and carefully: Don't rush! Smooth, controlled movements are more effective and safer. Focus on feeling the muscles working, not just on how fast you can move.

Don't lift your legs too high: Keep your legs at a height that feels comfortable and balanced. Lifting them too high can make you lose your balance and increase your risk of falling.

Engage your core muscles: Tighten your stomach muscles throughout the exercise. This helps support your back and improves your posture. Think about pulling your belly button towards your spine.

A strong core helps you stay balanced and prevents injuries.

This exercise works by making your stomach and back muscles work together.

To do it, sit on a chair with your feet flat on the floor and your back straight.

Slowly twist your body to one side, touching your opposite knee with your elbow.

Then, return to the starting position and repeat on the other side.

Keep your movements slow and controlled to get the most benefit.

Focus on keeping your back straight to avoid strain.

Start with a few repetitions and gradually increase as you get stronger.

This exercise is safe for most people, but if you have any back problems, check with a doctor first.

Adding this exercise to your workout routine can improve your overall fitness and balance.
