Which is better for heavy pressing?

The NordicTrack. It goes to 55 lb per dumbbell, while the MX30 stops at 30 lb.

Which is better for small weight jumps?

The MX30. Its offset dial adds 2.5 lb steps across 19 settings; the NordicTrack moves in 5 lb plates.

Is the NordicTrack worth $399.00?

It is the only one of the two with a listed price, $399.00 at Abt Electronics & Appliances as of November 8, 2026. That buys 55 lb per hand and iFIT access; compare it to the MX30's price before deciding.

The MX30 uses metal gears and nylon-coated plates, which should hold up well to frequent changes. The NordicTrack uses plastic-coated plates and a plastic tray, so treat drops carefully.

Do I need an iFIT membership for the NordicTrack?

No. The dumbbells adjust without it; the membership only unlocks the 10,000+ guided workouts and app syncing.

Which takes less space?

Both are compact. The MX30 dumbbell is 9.5 in long at 7.5 lb; the NordicTrack uses rounded plates and a tray, with a listed width of 19.4 in for the package.
