🎯 The Philosophy — Why DUP?
Once you’re intermediate, training the same rep range every session stops producing results. DUP varies the stimulus within the same week. Rhea et al. (2002) in the Journal of Strength and Conditioning Research found DUP produced 28.8% strength gains vs 14.4% for linear periodisation over 12 weeks in trained subjects.
