If you're looking for alternatives to the Supine Windshield Wipers exercise that target similar muscle groups, consider trying the following exercises:

• Half Wipers (Bent Leg): This exercise also focuses on the obliques, but with a bent leg position, which can make it more accessible for beginners. The movement involves lowering your knees to one side while keeping your shoulders flat on the ground, promoting core stability and flexibility. You can learn more about it here.

• Lying Butterfly Exercise: This exercise primarily targets the hip abductors and can complement your core workout by enhancing flexibility and strength in the hip area. It involves lying on your back with the soles of your feet together and knees falling outward, which engages the core while focusing on the hips. Check it out here.

• Straight Leg Wipers: Similar to the Supine Windshield Wipers, this variation keeps the legs straight and focuses on engaging the core more intensely. It requires you to lower your legs to the side while maintaining a straight position, which can enhance core strength and stability. You can find more information here.

Each of these exercises offers unique benefits while still targeting the core and hip muscles. Try them out and see which one works best for you!
