Street Parking Power is a weekly additional workout that includes the "slow" lifts such as back squat, deadlift, bench press, strict press, front squat, weighted pull ups or dips.
One of the best ways to increase metabolism and build muscle is by lifting heavy. People often miss this entirely when trying to get lean. The hormonal boost that can come from this will send your calorie burn into hyper drive! Getting stronger can also really help to improve how the weights in the other workouts feel and allow you to move them more efficiently.
