1. Plank:This is a great exercise for strengthening your core and developing your abs. Start in a push-up position, with your hands under your shoulders and your body in a straight line. Hold this position for as long as you can, aiming for a minimum of 30 seconds.
2. Bicycle Crunches: Lie on your back with your hands behind your head, lift your legs and bend them at 90 degrees. Alternate touching your left elbow to your right knee and your right elbow to your left knee, while extending the other leg. Repeat for 1-2 minutes.
3. Russian Twists: Sit on the floor with your legs bent and your feet flat. Lean back slightly and engage your abs, then twist your torso to the right and touch your left hand to the floor. Twist to the left and touch your right hand to the floor. Repeat for 1-2 minutes.
4. Mountain Climbers: Begin in a push-up position, bring your right knee towards your chest and then quickly switch to bring your left knee towards your chest. Move as fast as you can, alternating legs. Repeat for 1-2 minutes.
5. Standing Side Bends: Stand with your feet shoulder-width apart and place your right hand behind your head. Bend to the right side, keeping your left hand at your side. Return to standing and repeat on the left side. Do this for 1-2 minutes.

Remember, consistency is key. Aim to do this routine at least three times per week for best results. And don’t forget to combine your workout with a healthy diet and an overall active lifestyle for optimal fitness and wellness.
