My first post ever. I'm looking for information/advice from Cathe or anyone. I was just reading about the 1RM and how important it is to the program. I have ordered the STS and am feeling frustrated as I don't think I'll be able to follow the program exactly. I am capable of lifting pretty heavy, but I guess I'm not supposed to because I had a lumpectomy and radiation a year ago. I ran a half marathon on March 18 and had the surgery three weeks later. The day of surgery I did a little yoga and only took the day after surgery off from exercise. I started back easy(warm up from exercise video and a 10 min walk). Up until about 6 weeks ago I had only used one to three pound weights; however, I recently read about women like me (50, had cancer, seriously into exercise-and still are). Some of the women even wrote about lifting heavy before their surgery and going back to it. My surgeon never knew how to answer my questions about exercise as he told me his usual patients were 70 and not exercising - so I have just proceeded cautiously on my own. I just finished a round of S&H (albeit not so heavy) and am now doing GS. I'm up to 20 lbs. for lower body (did B&G yesterday), 8 little reps with a 17.5 bb for biceps(also for chest press), and 6 lb for concentration curls, and 8lb for hammer. So am I stupid to try to do STS? Thanks for any help.
