I am a 27 year old female. I am a mechanic so I have a physical job. I am also very new to working out. I am looking to increase my strength and overall be healthy.

There are 2 main issues I am having. The first one is my schedual. I work 13 hour shifts, every two days with a 3 day weekend one week and working the 3 day weekend the next week. Ex:

Mon Tues Wed Thurs Fri Sat Sun.
Off. Off. On. On. Off. Off. Off.
Mon Tues Wed Thurs Fri Sat Sun.
On. On. Off. Off. On. On. On.

I am very interested in using dumbbells, cable machines and barbells, and learning how to do the main lifts. I have tried Ice Cream Fitness and upper/lower split programs. I prefer full body workouts but I dont understand how to break up these workouts to fit my schedual.

My 2nd issue, is that alot of the workouts Ive seen focus alot on size and am not looking for that. Does the fact I enjoy weight training mean I will get huge no matter what?

Thank you
