Go Rock Climbing In A Lake

Rock climbing and swimming are both great ways to stay in shape. Swimming keeps your entire body in motion, while rock climbing makes you use your arms and legs to make your way to the top. If you want a real workout, combine the two with the Giant Inflatable Climbing Iceberg. Just blow it up, and set it adrift in a large body of water (a lake is probably best) and you’ll be able to combine two of the best workouts around. And hey, if you fall off, you’ll land in the water, which makes the Gigantic Inflatable Iceberg better than a normal rock climbing wall. $6000 Source
