When my weight loss slowed quite a bit, I was advised to add strength training. Not as a way to burn calories but because adding muscle tissue raises your BMR (the base rate of calories needed to keep your bodily functions going). I am NOT the athletic type so weight training was new for me. The pandemic hit right around then so I ordered a set of dumbbells from Amazon and found a very basic, easy, beginner's routine on YouTube that I could do consistently. It's a 15 minute whole body routine and it's not too strenuous. My weight started dropping again almost immediately. And it kept dropping until I was below goal. The investment of 15 minutes, three times a week, has paid off enormously.
