More Strength Training Sets Linked to Muscle Growth, But Results Vary
• Doing more sets leads to greater muscle gain, even among those initially deemed "non-responders" to strength training • Strength gains don't always correlate with muscle size gains; 4 sets was better than 1 for size but not strength • What works for some doesn't work for all; among responders, only 51% had better size gains with 4 sets & 15% did worse • Takeaway get stronger with 1 set but do more sets if your goal is to gain/maintain muscle mass • If what you're doing isn't working, try changing it, even if it follows the latest research
