Usually when I'm grounded somewhere I head to the gym about 5x per week, doing a weight routine. It's a bit more difficult being on the road. Not getting enough calories, nutrients (at times), energy, etc. to work out. However, I do use my knowledge of body weight workouts to still complete some...

My complete lack of muscle defenition and endurance is beginning to bother me. What's the best way to go about starting a calisthenics/strength training routine that can be done anywhere and doesn't require any equipment.
