What do you do when you need to burn off some steam? A lot of us check in at the gym. The idea behind Great Play is that, in an age when we're being bombarded with news about childhood obesity, maybe the kids should be doing the same. That's the whole point of the national franchise operation, which recently made its debut in the Denver area. Unlike other sport facilities for kids (specifically, kids ages six months through elementary-school age), Great Play offers a number of programs under one roof, from age-specific classes to open gym time, when children can just untether after a morning of too much TV. Also — and of great importance to the founders of Great Play, Englewood residents Keith and Jyl Camhi — is the non-competitive bent of the instruction, which encourages children to have fun first, and to learn specific skills (how to throw a ball or swing a bat, for example) in easy increments. It's their way of proving that exercise is good for you and therefore something worth encouraging; the goal of the Great Play method is to make it a natural part of kids' lives as they grow. The Colorado Boulevard gym is the first of several planned in the state (another will be opening in Highlands Ranch soon). In gymnastics vernacular, Great Play sticks it!
