How can you do a full body workout on the road with NO gear?
Legs:
One legged squats
Single leg dead lift
Chest and Tris:
Push-ups (one legged, one armed, feet on chair) or
Bench your girlfriend if she's heavy enough
Back and bi's?
Remember no chin up bar, so what can we do?
Feet on a chair facing the ceiling and grip the edge of a desk from underneath, pull yourself towards the desk. That's the best I could think of.
Curls with a suitcase in one hand or use a heavy bag.
Shoulder:
Handstand next to a wall and lower head to ground and back up.
Tri's
Dips between two chairs.
