What is a good upper body weightlifting routine that I could do daily to gain muscle without leaving a day for rest in between? How can I split upper body exercises in 2 halves so that I let the rest of the upper body rest in between?
Background: I would like to do a weightlifting daily workout session over holidays (2 weeks) on a well-equipped gym, so I would like to have my weightlifting sessions fit in so that I can do as much as possible. During the year, I only do maintenance weightlifting twice per week, and the rest is x-trainer and running.
