Question: how many reps and sets for a beginner?
Answer: Three to four sets of eight to 10 reps is a good range, Trink says. Start off closer to 3×10 (three sets of ten reps, which is about the same as you were lifting before) and every six to eight weeks, subtract reps and add sets. “The lower-rep range will force your muscles to adapt to the heavier weight,” Dell says.
