Concept2 RowErg

The single piece of home gym equipment that won't end up on Craigslist in eighteen months. Air resistance scales perfectly from your grandmother to an Olympic hopeful, the wood-and-steel build will outlive your mortgage, and the stroke is so satisfying you'll actually want to do cardio — a genuine first. It's whisper-quiet, folds in half, and has a resale value that borders on a meme. Buy it once, row forever.
