Yoga is a great way to improve your fitness as it can help to build strength, flexibility, balance, and endurance. Here are some yoga poses that you can incorporate into your fitness routine:

• Plank Pose – This pose strengthens your core, arms, and shoulders. Begin in a push-up position with your arms straight and your hands shoulder-width apart. Keep your body in a straight line and hold for 30-60 seconds.
• Downward-Facing Dog – This pose stretches your hamstrings, calves, and spine while also building strength in your arms and shoulders. Begin on your hands and knees, tuck your toes under, and lift your hips up and back. Keep your arms and legs straight and hold for 30-60 seconds.
• Warrior II – This pose strengthens your legs, hips, and core. Begin in Tadasana (Mountain Pose), step your left foot back, turn your left foot out, and bend your right knee. Extend your arms out to the sides and gaze over your right fingertips. Hold for 30 seconds and repeat on the other side.
• Tree Pose – This pose improves balance and strengthens your legs and core. Begin in Tadasana (Mountain Pose), shift your weight onto your left foot, and place your right foot on your left thigh. Bring your hands together at your heart center and hold for 30 seconds. Repeat on the other side.
• Bridge Pose – This pose strengthens your glutes, hamstrings, and core. Lie on your back, bend your knees, and place your feet on the mat hip-width apart. Press your feet into the mat and lift your hips up towards the ceiling. Hold for 30-60 seconds.
• Chair Pose – This pose strengthens your legs, hips, and core. Begin in Tadasana (Mountain Pose), bend your knees, and lower your hips as if you were sitting in a chair. Raise your arms overhead and hold for 30-60 seconds.

Remember to listen to your body and modify the poses if necessary. It’s important to consult with a qualified yoga teacher or healthcare professional before starting any new exercise routine, especially if you have any medical conditions. Also, it’s a good idea to warm up before starting any yoga practice, and to end with a cool down, such as Savasana, to allow your body to relax and recover.
