Do a water workout in the hot tub

Bathing in the hot tub is a wonderful way to relax, but with the right instructions, you can also exercise in the tub. Water exercise is great for joints and tissues, and water resistance makes the movements more effective. The warm water also stimulates blood circulation. Physiotherapist Teija Simola has created a workout in a Kirami hot tub that everyone can do in their own tub.
