First of all we can't comment on your progress because you never said where you started at. If you were doing 100 and 130 a year ago then your progress sucks. If you were doing 70 and 90 a year ago your progress is excellent.Second, you can't compare your progress to someone else's. There are far more variables than just training and some may be out of your control.Not everyone responds the same way. If your friend has been doing what he has been doing for a year now, then clearly he isn't going to burn out, but you may. I know I would.Again you need to define what progress actually is, and if it really is poor, then you need to discuss with your coach the kinds of training variations that you can experiment with. If your progress is good, then you need to be patient and let your coach do his thing.
