It's been a few months now that I've
been using the Krankcycle in my rehab process in the hopes of retaining some amount of cardio fitness for when I can finally (fingers crossed) get back to some version of running. There is still a looooooong road ahead of me but in terms of using this unique arm bike machine I thought I'd give a little progress report or at least my opinion of it.
The Krankcycle is actually an invention of one Mr. Johnny G (check out Krankcycle.com) who in the fitness world is a kind of guru in that he was also behind the hugely popular spin bikes and started the whole spin class movement. Well, he took the same idea behind his bikes (a dial to adjust the tension level) and applied it to an upper body workout. It builds off of the more standard UBE Machine (arm bikes that are used in rehabilitation commonly for older people or those unable to use anything below their waists...looks like I now fall into that category!) but differs in that it is much more versatile. You can adjust of course the tension level, the same as you can on a typical UBE, but you can also lift the height of the arm cranks so you can vary which sets of upper body muscles you target. You can further flip the pedals around and then cycle in either a forward or backward motion; neat if you want a change of pace. Finally, if you are able to use your legs the seat does come out and you can stand; the layout of the Krankcycle also encourages you to sit up straight (some UBE machines have a back and you can slouch back) and this works and tones your core. So, my first assessment was that it was indeed much more progressive and advanced than a typical arm bike.
That being said, there was still a period of getting adjusted to the machine and how it works. This goes for any kind of exercise machine that you choose to use in your fitness routines but especially being that I was a runner and not used to using solely my arms for cardio work it took a little longer to get used to. I first tried the UBE machines and will admit that because muscularly my arms were weaker I had a hard time generating enough power to get my heart rate into what I had wanted to be my target zone (or being able to go as long as I would have like!). Still, over time I got used to the motions and that alone made me improve and I could extend the amount of time on the machine; by the time I then switched over to the Krankcycle I still had to tweak my form and propulsion a bit but when I finally 'got it' I must say I was able to get in a good cardio effort.
On Johnny G's website he notes that the science behind the Krankcycle is still evolving and there are lots of tests that are still being done. For instance they aren't sure how getting in cardio work sans any lower extremities will translate to fitness levels when you then go back to running. They also aren't sure on exactly how many calories per say the machine burns; if it has a similar amount compared to other cardio machines or not. They do note that obviously because the arms are a smaller muscle group it will be less, but that you are able to elevate your heart rate enough so that it still is excellent exercise. One study from the American Council for Exercise estimated it burned about 9 calories per minute on average during one of the Krankcycle classes, think a spinning class but with these upper arm bikes.
There is also the theory that because the arms are closer to the heart this machine is able to raise heart rate level faster than if you were doing lower body cardio work. In my experience I won't necessarily say I found that to be the case, but I will say that the potential to get your heart rate up there is definitely there. After I became acquainted with the motions I was able to
incorporate interval workouts and tempo sort of efforts on the machine and I'll tell you I was definitely sweating, working hard, and my heart was pumping. By the end I will acknowledge I knew I put in a good effort. The only disadvantage I see is that because the arms are a smaller muscle group, and especially since mine are not as buffed as they could have been should I be say a rower, the amount of time I can go on the Krankcycle is significantly less than if I were running outside. But, for what I do I make sure it is high quality and with the intervals I know by the end I have stressed my cardio system and I feel good in that at least I am able to do SOMETHING to get my heart pumping.
I had been, and still am, dying being stuck on this couch!! :P
Time will only tell how this kind of cardio workout will translate into getting back to running, or at least even on the elliptical, but I will say that being that I have no other options for cardio the Krankcylce is something I'd recommend to anyone else in a similar situation. As with anything,
a major factor is how much effort you put into it and if that is there I believe I will be able to retain some amount of cardiovascular fitness. I know it won't be the same as where I was but it has to be better than nothing! ;)
Hi Caitlin - were you able to keep using the Krankcycle? Any new comments based on using for longer?
I'm looking for a hand ergometer for my wife (she has MS), but it's been hard to find long-term reviews of any of the options. Thanks!
