If you're looking to tone and strengthen your lower abdomen and legs while reducing belly fat, here's a 2-in-1 home workout routine that you can try. Start with leg lifts: Lie on your back, raise your legs straight up towards the ceiling, and slowly lower them back down without touching the ground. Aim for 3 sets of 10 reps. Follow this up with squats: Stand with your feet shoulder-width apart, lower yourself into a sitting position as if sitting in an imaginary chair, and then stand back up. Aim for 3 sets of 12 reps. Remember to maintain proper form and gradually increase the intensity as you progress.
