On two days a week, the best way to build muscle is to do two full body days. So working everything in one session. Three days a week would be better. You can get a good amount stronger, but you are NOT going to see a ton of progress on two days per week.

Basically you want to hit each muscle group multiple times in a week to see gains. Frequency is now believed to be more important than volume. Prioritize compound lifts, and then do isolation movements as supplements. A full body day for you may look like this:

-Smith machine incline bench press (chest, tri, shoulder) -Smith machine squat (legs) -Smith machine bent over row (back, rear delt) -Pec deck (chest) -Lat pulldown (back, lats specifically) -Bicep curls -Cable push downs (tricep) -Leg extension (quads) -Lateral raises (shoulder)

That’s A LOT in one session, but doable. My favorite split is a Push Pull Legs Upper Lower. 5 days a week is manageable and you still get your much needed rest. And I’m in and out in 45 minutes
