Today I went to the gym for the first time to get the program from my trainer. I warned him I have protuding disks in my lumbar and neck areas (lumbar L4-L5 and neck C4-C5). I am going through physiotherapy and I got relevant improvements in the last two weeks, after years of pain and difficulty in moving and occasionally walking. I am around 70 kg, 180 cm. Completely out of training, generally fragile.
The program mostly involves cardio (bike) for heating up (10 min)-cooling down (20 min), and machines to strengthen various muscles. I am a complete ignorant on this regard, but I went through 7 machines, one for the lower back, one for the abdominal (both involved bending my back forward) two for the legs, one for the arms, biceps and so on. I am sure you know which machines I used, but this is a sample of some of them.
I worked with 15 kg in most machines, doing 15 repetitions of the movement every time. I did the full round of the seven machines only once, but I am supposed to do two rounds each time, twice a week.
The point is that after this exercise, now my back hurts as it used to before starting physiotherapy. I don't know if it's expected, nor I know if I can actually bend my back in those machines considering my situation. Do you think the work plan is appropriate, or should I skip those machines ? Alternatively, what can I do to improve my situation ?
