4 Killer workout moves you can take to the park

You probably don't know that simply by taking your running routine out of the gym you increases calorie burn by about 5 percent, thanks to wind and varied terrain. Or that the work your body does to keep its thermostat steady while outside helps you torch calories by yet another 7 percent. Between that and the stress-reducing bennies of being in nature, it's enough to make us ditch the fluorescents for the sun.

Why the park for your workout? It has fantastic fitness tools, like swings, benches, and monkey bars. We asked exercise physiologist Tom Holland, a personal trainer in Darien, Connecticut, to put a new spin on some of his favorite moves of all time-squats, lunges, and chinups.

Do these moves shown below as a circuit-­going immediately from one move to the next. That's one set. Rest for two minutes, then repeat for a total of three sets. Nice work. You've earned a trip to the Good Humor truck.

BENCH JUMP Works core, glutes, hamstrings, quads, and heart

Begin by standing on a one- to two-foot-high backless park bench with your knees slightly bent and your arms straight out in front of you at shoulder height (A). Jump down so you're straddling the bench (B). Jump back onto the bench, landing with your feet together. Continue jumping down and up as quickly as possible for 20 seconds.
