1. Luggage Shoulder Presses and Raises

Press your bags overhead or do raises (front, rear or lateral) with them. When doing presses, grip the luggage on both ends and press the whole thing directly overhead (it's a shorter range of motion). If your luggage is light, you'll need to do high reps or isometric holds at the top of the movements.

2. Horizontal Push-Ups

These are done by first bracing two chairs against a wall about 2 feet apart. Kneel down in front of them then put your hands on the chair legs. Use your legs to push your body forwards then use shoulders to press your body backwards - use your thighs to apply resistance.
