Sandra Bullock's Workout for The Proposal

Eden Paul, a L.A. based trainer, designed a workout for Sandra Bullock for her role as Margaret Tate in The Proposal with Ryan Reynolds. The workout includes plyometrics, weights, Pilates, and boxing. The routine, which Bullock did three to four times a week, takes about 35 minutes.
• Warm up for 5-10 minutes. Paul recommends hopping on the treadmill and walk at a pace of 4.0
• Alternate three sets of 20 standing squats with three sets of pushups (do as many pushups as you can in good form)
• Alternate three sets of 20 reverse lunges with three sets of 15 dumbbells deal lifts
• Alternate three sets of 15 side lunges, alternating sides, with three sets of 20 dumbbell bicep curls to shoulder press
• Lie face up in a crunch position and scissor kick the legs for as many seconds as you can in good form. Rest and repeat three times.
