Question: A 30-year-old member at your fitness center has been weight training for 4 months and claims to have made significant gains in strength. Twice a week, he performs 1 set of 12-15 repetitions using 8 weight machines. Over the last 6 weeks, he's noticed that he isn’t achieving the strength gains that he’s used to. How would you modify his training routine to optimize gains in muscular strength?
