where do i buy heavy adjustable dumbbells? i'm looking for a set that exceeds 180 kg / 405 lbs (90 kg / 203 lbs per dumbbell) as a replacement for barbbells for lifts at home with the goal of doing 1 / 2 / 3 / 4 but for beta dumbbell lifts.
are there even 200 kg / 440 lb (100 kg / 220 lb per dumbbell) adjustable dumbbells out there? or is lifting basically only possible with barbells at a well equiped gym/home gym (to avoid barbell guillotines)?
what level of volume would you need to perform 1 / 2 / 3 /4 with less weight (e.g. with a 100 kg / 220 lb dumbbell set (50kg / 110 lb per dumbbell). if 1 / 2 / 3 / 4 is your 1RM then i dont think doing 1 / 1 / 1 / 1 for 1 / 2 / 3 / 4 reps is the same thing, but i dont know what would be.
how much mileage could i get out of a 100 kg / 220 lb dumbbell set? it might be more reasonable and i could at least aim of a 1 pl8 OHP 1RM. i dont even know if there are 50 kg / 110 lb per dumbbell adjustable sets out there but it might be more likely to be a thing that exists
