what muscles do you build when you bike
The two largest muscles that riding a bike targets is your quadriceps and your hamstrings. These muscles contract in a sequence that creates the pedaling action. The quadriceps and hamstrings do most of the work when you ride a bicycle.
Although riding a stationary bike is predominantly a lower-body and cardiovascular exercise, your upper-body muscles get in on the act too. As you lean forward on the handlebars, your triceps, deltoids and pectoralis major muscles must work to support your weight.
