Gravity is Free
Calisthenics build incredible physiques. Look at gymnasts. Pushups, squats, lunges, burpees. You can modify these infinitely to make them harder.
The Great Outdoors
Find a park. That bench is for step-ups. That tree branch is for pull-ups. That hill is for sprints. The world is a playground.
Household Objects
A gallon of water weighs 8lbs. Put books in a backpack. Lift your couch. Resistance is resistance; your muscles don't know the difference between iron and a jug of detergent.
No Excuses
The barrier to entry is zero. You don't need a membership. You need a floor and the will to sweat.
