Cass Martin on Instagram: "Cardio is strength when you do it right, and the @nordictrack X24 Bike powered by @ifit proves that. With 24 resistance levels, a 20% incline, and a 10% decline, every ride challenges both my heart and my muscles. SmartAdjust automatically tunes the workout to my pace, so all I have to do is show up and move. It’s not about doing more. It’s about doing it smarter.
