Alexandra Daddario, star of this summer's Baywatch, worked with co-star Zac Efron's trainer Patrick Murphy to get in big-screen shape. To get visibly defined muscles like her, try this total-body workout from Patrick himself, packed with the moves Alexandra did, two or three times a week on nonconsecutive days. Do this routine as a circuit: Complete 15 to 20 reps of each exercise, moving from one to the next without resting. At the end, rest for two minutes, then repeat two more times for a total of three sets.

FORWARD LUNGE WITH FRONT RAISE

Stand and hold a pair of dumbbells at your sides (a). Step your right foot forward and bend both knees to lower into a lunge as you raise the weights in front of you to shoulder height, keeping your arms straight (b). Press through your right heel to return to start; switch sides. That's one rep.

RESISTANCE-BAND PUNCH

Anchor a resistance band around a stable object behind you, at chest level; hold one end of the band in each hand (a). Step your left foot slightly in front of your right as you punch forward with your left arm, keeping your right arm still (b). Reverse the movement to return to start. That's one rep. Switch sides.

Step your left foot back and bend both knees to lower into a lunge as you pull the band with you, squeezing your shoulder blades together (b). Stand to return to start. That's one rep. Switch sides.
