Part of the reason actors and models look so toned in the pages of magazines is that they utilize quick workouts that pump up their abs, chests, and arms minutes before baring their bodies. Why shouldn't you do the same before you hit the beach? "I like to utilize a dynamic/static/dynamic approach," says Logan Hood, a former Navy SEAL and the owner of Epoch Training in Los Angeles, where he counts physique-conscious stars like Zac Efron and Jason Statham among his clients. "The key is to move as explosively as possible after the hold. This creates a decent pump without a lot of sweating." Here's Hood's quick, get-ripped-now regimen for the beach.

THE CIRCUIT
(Repeat four times)

Pull-ups
Do three standard pull-ups. Pause at the top of the third rep, keeping your chin above the bar. Hold for 10 seconds, then lower your body and do three more reps.

Push-ups
Do four standard push-ups. Keep your abs tight and your back straight. On the fourth rep, lower your body until your chest is an inch off the floor and hold for 20 seconds. After the hold, do four more push-ups.

Body-Weight Squats
Keep your back straight and bend your knees until your thighs are parallel to the floor. Push up through your heels. That's one. Do five. Pause in the low position of the fifth rep. Hold for 30 seconds, then do five more squats.

Hanging Knee Raises
Jump up and grab a bar with an underhand grip. Keep your arms and back straight and raise your knees to your chest. Do six reps. Pause at the top of the sixth rep and keep your knees close to your chest. Hold for 40 seconds, then do six more.
