Can it be done? Perhaps with a tonnn of pushups/crunches etc? I'm not very well off financially, so joining a gym is out of the question. I don't own any exercise equipment. Let's say for all intents and purposes; I can only use what's around the apartment. Can I still build up arm/upper body muscle and then tone it?
I have veryyyy little experience with working out. I'm like 5'9'', and only 135lbs. Arms are skinny as Hell, no abs, no upper body strength whatsoever. Anyone have any friendly and constructive advice? Googled a bit, but only found workouts involving a home gym.
