Chisco Ruiz: I have recently started training on the Concept 2 at my local gym and must say I am enjoying it very much. However, I have inquired with my fellow rowers and no one can come to an agreement as to what is the proper breathing technique. When should I inhale and when should I exhale? Terry O’Neill: When you are working aerobically you will need one breath per stroke, normally breathing in on the way forward and out on the way back. As you increase the intensity, you will need to increase the breathing rate to two breaths per stroke, in and out coming forward and in and out going back. Having said that, at the end of the day there's no hard and fast rules: just breath as seems natural and easiest for you.**********************Debbie McGreevy: I am the proud owner of a new Indoor Rower and I would be grateful if you can tell me how to stretch out my rhomboids and trapezius muscles post exercise? I get really bad pains mid shoulder blades. Am I exercising correctly and what can I do to stretch this area?Terry O'Neill: The rowing machine should not cause you any pain but it will expose any weaknesses you may have or injuries carried over from other activities. You should see a doctor or physio if the pain persists, but all the stretching exercises can be found in the Training Guide or on our web site at http://www.therowingcompany.com/v4/stretching.htm. **********************Michael Crow: In your 6 month weight training plan for 2,000 metres, on weeks 7-12 you have not said how many circuits should be completed, or am I completely blind? Let me know and keep up the good work. I think the training programme is really challenging.Terry O'Neill: You are right it is not clear. This is the strength building stage and the intensity is controlled by weight increase as opposed to increased circuits. So you do two complete circuits of 20 seconds on each exercise with one minute rest.
