I need to start riding a bike. My butt is flabby and my legs are weak. I'm gonna ride a bike or I'll never live to see another day.

I'm gonna ride a bike or I'll never live to see another day.

My legs are weak and I'm gonna die if I don't start riding.

I need to ride a bike before my body gives up on me.
