I have noticed a larger and larger community asking about alternatives to working out in a gym. I understand one element of being primal is "lifting heavy things" which I'm all for, but I know many who want to work out primary muscle groups like back, chest, and legs using body weight or the environment around them.

So I pose the questions: What are some solid work outs for these three main muscle groups, Back, Chest, and Legs.

Second: What are good exercises that isolate or incorporate (I'd like to hear both), secondary muscle groups like arms (biceps, triceps, shoulders), abs/core, calves, traps, etc.

I am going to create a catalog from your answers and practice them to eventually share with others, so all input is much appreciated and encouraged ^^

Thanks guys
