Exercising On Vacation

I really want to continue and actually increase my exercise level. I have gone swimming a couple of times per week for the last month or so. It makes me feel so good and I think I am tightening up some. Now I need to increase that level. Burn those calories! Relieve that stress! I will definitely take my swim suit to swim in the ocean and pool. And for walks along the beach. All good for exercise. I need to take my tennis shoes too for good long walks. Some people have started talking about mbt shoes for exercise, but I don't know anything about them yet.
