Comming back after chest injury Need help

[WorkingoutPete]

Level of fitness: not sure I have been working out for 2 years off and on, but recently from december 3rd to march 4th I worked out 4-5/7 days a week with only missing 4 days due to minor injury or the flu. I took a 2 month halt cause I injured my sternum doing yoga, it's oook now still cracks into place but no pain... in that meantime I only worked at my job as a dishwasher which requires some amount of fitness either then that no I sat around all day.

Current weight: 135lb about 15%bf ectomorph with my diet + workout (see below) I was gaining half a lb a week.

Goal: to go from 135lb to 160lb of lean muscle without supplements.

diet(before injury, ate less while injured but stuck to it best i could, trying to get back to it): ttp://img833.imageshack.us/img833/1574/unlednp.jpg [copy and paste url add the letter h to the beginning]

What I have: A bench (it has some leg exercises stuff with addable wieght), barbell, about 250lb of assorted weights, 2 customizable dumbbells, garage has support beams i can do chinups on.

DAY 6 back to arms shoulders

Thoughts: My chest has always been weak, maybe thats why I injured it. I did a workout today did bench press and pushups with no pain but was weak probably due to inactivity (I pushed it to the limit). I still wanna take it easy on the chest too be safe it still cracks when i stretch wiered. AB routine sucks I hate doing lots of situps (gives me a rash) but I wish I had a heavier weight or another exercise. Trying to avoid cardio because I can't afford to lose weight.

Any help is greatly appreciated.
