It only takes 80 minutes a week to reach your fitness goals, according to SHAPE’s Fitness Editor-at-Large Jay Cardiello. His new 6-disc DVD set, JCORE Accelerated Body Transformation ($105; jcorebody.com), promises to help you shed pounds and firm up in just 40 days. Each disc contains a different 20-minute workout (ranging from explosive plyometrics to rejuvenating yoga) that can be done in your living room (no gear required!), even if your apartment is New York City–sized. You also get a meal plan with recipes and a shopping list. Need extra encouragement? Log onto jcorebody.com every Wednesday at 9a.m. EST to train with Jay in a live-streaming session. This year you’re getting in shape—no excuses.
