Jumping jacks. Jump rope. Rope climbers. Lunges with weights. Pushups. Crunches then stretch. Your done in twenty min. And you have gotten your heart rate up and your metabolism revving.
How much time do you have before you have to leave for school?
I have about half hour depending what time I wake up
you can do a total-body strength training routine. If you have a little money to spend, invest in a pair of 5- and 10-pound dumbbells and an exercise ball. Hold the dumbbells and do biceps curls, triceps extensions and side raises to work the arms and shoulders. Hold the weights at your sides as you do lunges and squats. Use the exercise ball to do crunches for your abs, planks for your core and shoulder bridge exercises to work your butt and hamstrings. If you don't want your office to be filled with exercise equipment or you can't invest the cash, do planks and pushups for your upper body, lunges and squats for your lower body, and crunches such as the bicycle crunch and reverse crunch for your core. Stick to your schedule and you'll find that even in 30 minutes a day, you'll start to slim down and feel better.
