Punch It UpWork your way to a better body at a pro boxer’s new gym.The last time we saw local boxer DaVarryl Williamson, it was early 2006 and he was preparing for the biggest fi ght of his life—the heavyweight cham-pionship of the world (“A Touch of Sleep,” February 2006 issue of 5280). It was a fi ght he lost, but today Wil-liamson has poured his talent and disci-pline into something else: a new gym in Englewood, dedicated to the everyman. Whether you’re a box-for-the-fun-of-it amateur, a new mom trying to get back to “fi ghting weight,” or a teenager in need of some structure, Williamson’s hardcore studio, Touch ’Em Up Boxing (www.tosboxing.com), will whip you into shape without machines, weights, or Pilates. Each class is just $10, so no excuses. Plus, the last half of each session is inside the ring with Williamson—gloves on, hands up, workout-ready. Below, Wil-liamson’s top moves for trimming your physique this spring. —SARAH RUMPLE

> If only you’d joined the track team instead of bumbling through peewee football...Who knows, you could’ve been a contender. DNA testing won’t help you now, but it can save your o� spring from similar regrets—so says Boulder-based Atlas Sports Genetics (www.atlasgene.com). The company sells DNA test kits ($169/Atlas First, $999/Atlas Pro) to help parents steer their kids toward sports that suit them best. ¶ Here’s how it works: Swab the inside of your child’s cheek, send the sample to the lab and, within a few weeks, receive an analysis of ACTN3, a single gene (though you have two copies)—out of the human genome’s 20,000— with a proven link to athletic prowess. If neither gene copy possesses a variant (mutation), the gene produces actinin, a protein in fast-twitch muscles needed for power events like gymnastics and football. But, variants on both gene copies block actinin, indicating a predisposition toward endurance sports. The test doesn’t guarantee an Olympic career, but it might help your little ones get the most out of their extracurricular activities—while you relive those glory days you never had. —JAYME OTTO
