If you have a cast-iron frying pan or a heavy pot, you also have access to a dumbbell when you are in the kitchen. The is a lateral shoulder exercise you can do when you have a minute to spare when preparing dinner.
Grab your cast-iron frying pan with your palm facing down. Raise and lower the pan slowly to target your shoulder. Repeat for the desired number of repetitions and then switch to the other side.
You can adjust the level of difficulty by changing the angle of your elbow and how you are holding the pan. To make it easy; do the exercise with your arm bent and holding the pan with the pan area below your hand. To make it more challenging; straighten your arm and make sure the pan is pointing forward.
You can also use the pan for other dumbbell exercises; why not try to do some good old curls?
