I agree with Scott. If you’re already rehabbing then I would not invest in something that has cause you pain in the past. If you’re looking to go with legs I’d probably say incline trainer is your best bet.
Only downside is they don’t fold like treadmills do, but the difference in 12% incline on a treadmill vs 40% on the incline trainer is massive.
Read around on stuff here that helps explain what they’re good at and what they aren’t good for and see if it’s up your alley.
I think the only differences in the NT incline series is the size of the screen, but I could be wrong.
– Scott, which one do you have?
