Walking lunges can be a great way to strengthen the muscles of your butt, hips, and legs. But you can get more bang for your strength-training buck if you do your walking lunges uphill. The extra effort works your muscles harder and can help build strength faster. Find a walking route with some hills. Then do 2 to 3 sets of 5, 10, or 20 lunges during your walk. Just make sure you engage your core muscles and keep your knees aligned over, but not beyond, your toes as you go.

If you have any health issues or haven’t been active in a while, please check with your doctor before starting any new exercise routine.
