How many weeks are you planning on doing this for?
If it's only a short setup; then ya start thinking of other stuff. But if it's something you should be on for a few months....relax your brain.
And as far as "what should i do next?"....we can't really answer that.
It's 100% personal. I know what I'M doing next....and what other people I know SHOULD do...but it's all up to them.
Figure your goals, find some good threads on workouts....pick out one or two..and tweak it to fit YOU.
