What should I do ?

Tweet

I live in a condominium, and there is a common gym room for everybody to use. I go there every morning to exercise for about 45 minutes. There is not a lot of people using it in the morning and that's why I like to go there first thing after I wake up. I usually do 30 on track mill and 5 minutes on sit-up, 10 minutes on muscle toning on my bicep and tricep. There is another regular, a Caucasian in his 50s. Well, he likes to do weight training as well, but he do it like a round-robin, he will go around each instrument/machine, doing 1 set of workout at each one and then to another, in many many rounds. But for me, I would like to do my bicep toning 4 sets in a roll, with 10 to 15 seconds interval, then move on to tricep and 4 sets, and then I am done for the day. Usually this is not a problem, but this morning, just happened that while I was just about to start my bicep workout, he started to go his round-robin thing. When its time for his bicep workout, I was in my 3rd set, and he said out loud at me "Haven't finished already ??!! Jesus !!!" ( meaning I was occupying the instrument ). Then I quickly stopped after my 3rd set, and went to my tricep workout. I was upset then, I was cursing a lot in my heart. But then after my bath, I cooled down , I am no longer angry with him and I thought to myself, I should not have given up, I used the machine for 5 minutes at most, if he has a problem to wait for 5 minutes, that is his problem, isn't it? What do you think? Am I wrong in this situation ? Should I give up my rights to use the instrument when he is doing his round-robin workout? Or I just ignore this man? Please advice.
