I don't have enough equipment to bring it outside.

For most workouts, I wouldn't be able to make the rest periods between exercises.
My workout has been pretty inconsistent during the last year. I couldn't workout for two months due to my shoulder injury. I still could play basketball, and I did that and cut some calories back. I cut a little too much back and dropped from 192 lbs to 178 lbs. My shoulder frustrated me to no end, but seems good now. Most workouts over the last couple months have consisted of squats, deads, and rows. Due to lots of basketball, the workout days have been inconsistent and I haven't been motivated (they hurt my game). But, that's finally past me. So, now I'm looking at working out again and hopefully putting on a 1/2 lb to 1 lb per week.
My overall fitness is great, even though my strength is down some. Basketball starts again in fall, and I want to be heavier and stronger. So, I was thinking of doing a premade routine or two before the cruise and get myself back into it (and for looking good), and then really hit it hard after the cruise on a very focused bulk.
