Background: New to TRP after the typical mess being a nice guy in relationships. Working on doing the groundwork for self improvement: reading sidebar material and RP theory.

I want to get serious about lifting, but at the present moment, I don't have access to a good gym. I can hit planet fitness for now, but it's all machines and even the squat racks and press are smith cages.

Question: In the interim, until I can find/afford a better place lift, does anyone have suggestions about the best way to maximize gains and minimize time using what I have available? I know the optimal is compound free weight exercises, but I don't have that ability at the moment.

Any advice is appreciated.
