I am new to working out at a gym since Jan.1st. I was told at my gym that the stairmaster stairstepper provides a great allover workout. Realistically, I can see that it doesn't work the arms. I have been using this machine for 30 min's each time I visit the gym (6 out of the past 7 days). My problem is that my ribcage and upper back is screaming in pain. I'm also doing weight lifting with alternating upper and lower body workout days.
Tonite, I did my routine for my hips and legs, plus did the stairmaster. Is it normal for me to be this sore? Is it just cause I'm new to the weight lifting or that I'm simply overdoing it and not letting my muscles have time to rest.
Should I alternate days on the stairstepper also and just walk on treadmill on the opposite days? Any help or advice would be appreciated. (prior to joining gym, basically my only form of exercise was walking).
