Update; Got the Concept 2 last Friday. Finally got to try it out Monday and have done a few workouts since. I am taking it easy and doing 15 minutes at a time at a 2:28/500 pace on the lowest setting. Couple more questions.
Is it better to breath in or out when pulling back on the bar? Does it make any difference.
The workout seems to be bothering my knees. I wonder if I am bending my knees too much (have terrible flexibility) and it is causing the issue. Or if I am pulling back too hard or going back too far? My wife says my form looks fine.
Any ideas what might be causing the knee pain. I run 5 miles a day or cycle 25 and neither bothers my knees. I thought I had pretty sturdy knees.
