The great thing about core workouts is that you can do them almost anywhere. In your office, at home or at the gym. For most great core workouts you don’t need any weights or bars, just the weight of your own body.
1) Exercise ball workouts. There are tons of great core and abdominalworkouts you can do with an exercise ball either in your home or at the gym. An easy one is to sit on the ball with your feet flat on the ground and then keep your balance on the ball and cross your arms and do modified sit-ups. These exercise ball sit-ups are great because they force you to use your stabilizer muscles and tighten your abs to work both at the same. Another easy one is the butt lift, where you put the ball against a wall and then lean you back against the ball with your legs bent and flat on the ground and your arms at your sides. You then push your core up into the air so your legs are still flat on the ground and your body is horizontal. This is a great, though slightly acrobatic core workout.
2) Plank. The plank is a popular core position with a number of different variations. The one I like is a plank with a diagonal arm lift. Put yourself in a pushup position with your forearms on the floor. Then raise your right arm out and up and hold it for a few seconds. Lower and repeat with the opposite arm. This is a great workout for core strength as well as stability and it is easy to do anywhere.
3) Bicycle crunches. One of my favorite abdominal and core workouts, this one is a little more intense and will definitely have you sweating if you’re doing it right so you might not want to try this one on your break at the office unless you’ve got a change of clothes. Lie on your back with your hands behind your head (not clasped) and “pedal” your legs like you are riding a bike in the air while moving your elbows and body with your motions. So if you are kicking your right leg cross your left elbow over to your right side. And vice versa. Make sure you are focusing your brain on tightening your abs as you are doing your crunches for maximum effect.
