Dumbbell-only training is one of the most underrated setups. With a single adjustable pair — or even a fixed pair — you can run productive strength training for years.
RepRoute's generator filters the whole exercise catalogue down to what your inventory supports before it picks anything. Own dumbbells only, and you'll never open a session to find a barbell back squat or a cable row waiting for you. Movements that need an apparatus you don't have — a bar to hang from, a dip station — are filtered out too.
Be clear about where that filtering stops, though: RepRoute matches the equipment TYPE, not the load. It doesn't know your bells top out at 25 kg, so it won't refuse to program a movement on that basis — you're trusted to load the weight you can actually lift. Progressive overload then steps up by the weight increment you set in Settings → Preferences.
Goblet squats, dumbbell Romanian deadlifts and bent-over rows all double as compound work for legs, back and posterior chain. With a bit of creativity, a single pair goes a very long way.
