Vew-Do Flow Balance Board
More than 40 years ago, the balance board, then called the Bongo Board, became popular among surfers as a stability- and core-building exercise on land. Now that workout can be applied to general fitness. Spend five minutes a day standing to challenge your equilibrium. Then try to squat. The board's instability means any workout you do on it – including push-ups, planks, and endurance balances – will engage your core as well as the targeted muscles. [$120; vewdo.com]
DO THIS: Push-ups. With your hands balancing on either end of the board, hold a steady plank. Once you've mastered this, work your way slowly into a push-up. Repeat 10 times.
• Squats. Hold your arms out in front of you for balance.
• Timed stands. Simply stand on the Vew-Do for 60 seconds. Work your way up to five minutes.
• Ab rolls. Turn the board sideways and position your hands on it. With knees on the floor, roll out until your legs are straight, then roll back in.
• Advanced balance. Jump onto the board, catching your balance when you land.
