does ride a bike help
The Core Muscles. Your abs and back get a workout on an exercise bike, but only if you maintain your posture. If you slouch or let your abs sag, you won't see many toning benefits and you put yourself at risk of injury. On any bike, keep your back straight and your abs tight. If you ride a spinning bike, the forward-leaning position will work your back muscles more deeply than on an upright bike. On recumbent bikes, the reclined position helps you focus on your abs.
