You’ll burn about 25% more calories for every 0.5 mph increase, which is what each new level in the first 10 minutes of the plan below does. “This burns as much fat as possible in a short workout,” says Rocker. And getting your heart rate up will give you an energy boost that will last all day.

Step forward with left foot as far as comfortable. Land on heel, controlling descent as you bend knees and drop hips, keeping left knee directly above ankle. Don’t lean forward. Stop when left thigh is parallel to ground. Stand back up by squeezing glutes and pushing off with back toes; bring right foot next to left foot. Repeat with right leg, slowly lowering into lunge. Tree Sit Tones butt and legs Sit with back against tree trunk, fence, or wall so knees are bent at 90 degrees and ankles are directly beneath knees. (You can use hands to help you get into position or, if the surface is smooth, slide down into position.) Hold 20 seconds, then return to standing. Double Lift Tones abs and back Start on hands and knees with back flat. Tighten abs without sucking in. Raise and extend right leg behind you, parallel to ground. When you feel stable, raise and extend left arm forward, so it’s parallel to ground. Simultaneously raise and lower arm and leg 2 to 3 inches. Do all reps, then lower and switch sides. Reverse Curl Tones abs Lying faceup with legs bent, place hands under small of back and lift feet off ground so knees are over torso. Contract abs, pulling knees toward chest, and release without letting feet touch ground, then repeat. Avoid swinging thighs or raising hips; this is a very small movement. Triceps Dip Tones arms and back Sit on edge of bench, wall, or railing with hands grasping edge, feet flat on ground. Walk feet forward a few steps, knees over ankles, and shift hips just off bench. Bend elbows back as you lower hips to just below bench level. Straighten arms, pressing body back up. (If shoulders feel strained, don’t dip as low.)
