Thanks for the suggestions. I already own a weight vest, so it’s a bit of a moot point as it applies to me. I do have the others on the list, but don’t have a rower (I have an airdyne, though, which I prefer). Personally, I think the vest is a great tool to have and I use it for both workouts and short walks each week. I would certainly recommend it to others considering it.
I would add: olympic rings, medicine balls, 1-2 kettlebells, ab roller, and a neck harness (along with a weight vest) as great additions to a home gym. While none are as essential as squat racks, barbells, and dumb bells, they all get plenty of use in my routines.
