For years I've maintained a similar training cycle: chest/triceps, back/biceps, shoulders, legs, repeat. It's worked out well and I have changed it up every now and then: sometimes working shoulders in with chest and back, sometimes doing a leg excercise before ches and back, and sometimes doing legs/shoulders together. I would always try to work cardio in, but undoubtedly that's been an area where I have slacked off.Recently my training partner and I began a steady two month rotation:
- chest/triceps, back/biceps, shoulders, legs
- chest/biceps, back/triceps, shoulders, legs
- chest/shoulders, back shoulders, biceps/triceps, legs
- repeat
The first and third cycles are always great as your working similar muscles and they have more time to recover. The second cycle is cool because you can do more compound sets and the workout doesn't take as long. The third cycles is a good change because you can focus an entire workout on arms.
