Unless you plan on opening your own professional gym, there’s no reason you need to spend thousands of dollars on a treadmill. The NordicTrack T Series treadmills are seeing significant markdowns, with the standout 6.5S model now available for $664, down from its regular price of $799—that’s a solid 17% discount, saving you $135.

NordicTrack T Series 6.5S

If you ask me, the biggest selling point of this model is its space-conscious design. The treadmill folds away easily to maximize your room’s available space—a truly crucial consideration for home gym setups. When you’re ready to work out, simply press the black bar with your foot, and the treadmill will lower to the floor automatically.

My colleague Beth Skwarecki also recommends the 6.5S as a top option, and points out how other models in the T series line have great deals right now. If you’re looking for a smaller or more affordable option, the Series 5 is 28% off—down to just $434.

Perhaps the coolest part of joining the NordicTrack ecosystem is the access to over 10,000 workouts through iFIT. For $39/month (or $396/year), you can follow expert trainers through global runs, hikes, strength training, yoga sessions, and more, all while the system automatically adjusts your treadmill’s speed and incline to match the workout. And for those of us who like to track their progress across multiple platforms, iFIT syncs with your Strava, Garmin, and Apple Health.
