These days, I do most of my workouts at home too, but I am definitely lacking in equipment. Everything is so ridiculously expensive right now though, I don't know that I want to buy a lot more. I have an olympic cage that I can do squats, bench, lat pull downs, rows, etc in. Also have a bench that can go incline and some dumbbells, but am definitely short on those. Have a kettle bell and also some bands that I use for shoulder work and pull up assists at times.
For cardio, I have an old Lemond Revmaster stationary bike, a rowing machine, and an old treadmill. I'm thinking of upgrading the treadmill to either a newer better one, or maybe to an elliptical, since I know my wife would use that more. That arc trainer that
@AgEngDawg mentioned could be a good one.
