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 plan generator filters every exercise by your inventory before suggesting it. If you've got 25kg dumbbells, you won't see prescribed weights of 30kg — the plan just doesn't generate that lift.
Goblet squats, dumbbell Romanian deadlifts, and bent-over rows all double as compound work for legs, back, and posterior chain. With creativity, you can build serious strength with a single bench and a pair of bells.
