Lay on your back and extend your arms over your head. Hover your legs a few inches off the ground, with your feet together and your toes pointing towards the ceiling. Using your core, pull your legs and torso upward and try to touch your fingertips to your toes. Lower your body—with control—back to the floor and repeat. Reps: 20
Start the workout with push-ups. Make sure your arms are strong and slightly wider than shoulder-distance apart. Start in a plank position, and slowly lower your body until your chest hovers above the ground. Avoid sinking hips and don't stick out your butt. Return to plank position. Reps: 20
Don’t get off the floor just yet; get ready for ab-burning bicycles. Lay on your back and position yourself as if you’re about to do a sit-up. Raise your legs into a tabletop position, with your hands behind your head. As you lift upward with your core, twist to one side and extend your opposite leg straight. Alternate sides. Don’t rush it. When your muscles are burning, that’s when you’re being effective. Reps: 20
If you want buns of steel, there’s nothing more effective than a classic squat. Stand with your feet shoulder-width apart, then sit your bum back and extend your arms straight out in front of you. (The motion should be like sitting in an invisible chair; don’t let your knees come in front of your toes.) Hold for a few counts, then stand. When you come up, fully clench your glutes, Reps: 20
Here’s a killer for your arms: triceps dips. Find something in your room—like a chair—that’s lower than knee-height. Position yourself away from the object, and extend your legs forward. Keeping arms shoulder-width apart, bend your arms to a 90-degree angle, using the strength of your triceps to lower your body a few inches. Hold, then push yourself back up to your starting height. Keep your back straight and your core engaged. Reps: 20
Next up is sit-ups. Use a towel as a mat and lie flat on your back with your knees bent about hip-distance apart and your feet flat on the floor. With your hands behind your head and your elbows pointing outwards, exhale and use your core to pull yourself up into a seated position. (It’s OK for your feet to lift off the ground as you sit up.) Inhale as you lower back to the ground. Reps: 20
Always travel with a pair of gliding discs, which are easy to pack. To start, place each hand on a slider about shoulder-width apart. Position your body in a plank position on your knees, with your hands under your shoulders and your knees bent with your toes curled under. Keeping your core engaged, slide your hands straight out in front of you, reaching forward. Using your core, pull your hands back to the starting position.
Now use a glider for a single leg side slide lunge. Position yourself as if you’re about to squat, and put one foot on top of a glider. As you squat, extend your arms forward, and slide the foot that’s on the glider out to the side of your body, keeping your toes facing forward. Reps: 10 per leg
Next is the forearm plank. Keep your hands straight and your elbows shoulder-width apart. Keep shoulders in line with your elbows. Engage your core, and keep your bum tucked in. Don’t let your lower back sink. Hold for one minute.
