Well, whatever you are doing, you probably aren’t having as much fun working out as Mark from Mark’s Daily Apple.Com. What he is doing is exercising, but from the looks of the scenery and the people, it’s a dream day on the beach with a touch of added fitness. I have tons of sprint videos in my collection, but none look as enjoyable, relaxing, envigourating and satisfying as the one posted below. Along with the great instructions Mark offers on beach sprinting, this video just makes you think of every time you’ve ever gone to the beach and had a beautiful day. Then to add a level of fitness, a simple yet effective workout that only take 10-15 minutes, is more than anyone could ask, for a satisfying and purposeful day out. Try this before winter arrives. Enjoy.
