My knee has been killing me lately so I’ve been limiting my running and sticking to the bike or elliptical. On the latter I always worry that I’m not getting a good enough workout so I’ve been doing lots of great intervals. My favorite this week has been alternating between a crossramp of 4 and resistance of 3 at 190 strides per minute (almost a sprint) and a crossramp of 16 and resistance of 5 at 160 strides per minute (still an uphill battle!). I end the workout sweaty and with every part of my legs tired. Though it can’t replace running, I’m glad I can still get in some similar movements and keep my legs in shape.
