When do you know if your are over training or just pushing your limits? I mean.. you need to push the limits, and that will be tough and hard work, in order to get better. I can't run today, or walk. Because my body is begging me to rest my legs and feet, and I'm going to listen. Then I'm also pretty tired in my lower back from the weight lifting and the rowing I do for cardio (and probably also from running in my shoes). I should do more of the rowing cardio, because I need to be good at it for the competition I'm prepping for. I'm aiming for 2 times a week but want to do it 3-4 times a week. I just can't get up to that. I feel over trained and drained. And then I feel guilty if I give myself a rest day more than planned. Do you guys also feel bad if you don't get your planned training in? Should I suck it up and do the cardio and not feel bad and guilty for resting?
