Sometimes it’s just difficult to leave a cosy home and go outside, especially if it is rainy or cold. So what to do to get some exercise? Here are 12 exercises you can do in the comfort of your living room. You don’t need any equipment. To make these exercises more fun, you can blast music while you’re doing them. If you don’t have dumbbells but want to add some weight use water bottles. “A full 16-ounce water bottle weight approximately 1 pound and can be used in place of dumbbells for arm exercises such as arm curls, arm overhead extensions and arm overhead presses. If this is light for you, perform a higher number of repetitions, such as 15 to 30.”
