The week is good for trying new forms of exercise and finding the one (or ones) that you definitely enjoy. You’ll have to focus on your health, so dancing may be the best idea here. It’s great for your mind, your soul, and your body.
Dancing will firm up your abdominals and give you more flexibility, as this is a marvelous fitness practice. Not sure what dancing style to choose? Opt for the one that will encourage you to release your emotions and help you feel invigorated.
