Boston magazine: If you’re like us, you’d rather spend your summer days relaxing and enjoying the sun than heading to the gym. But what if you could do both? Instead of abandoning your plans to work out and opting for lunch on Newbury Street, grab a bike and take it for a spin on a destination bike ride or around the city —you’ll get a workout while relaxing and exploring. If you’re a member of Boston’s Hubway program, you can simply pick up a bike on your way down the street. If you need a bike and you don’t own one, there are plenty of rental shops around the city as well.
