Gyms have static, old-school machines, rigid bars, and weights that isolate one muscle group at a time. Some of these machines were designed in the 1970’s and don’t imitate real-life movements. Your brain will stop you from going back to the gym very quickly. Why? because it is painful and will hurt you.

At the gym, you often use equipment with sweat and grease from the previous guy on the bench, pay exorbitant membership fees, and waste time in commuting to and from the gym.

A recent study even found that gyms harbor more germs than a toilet seat.
