Evidence-based breakdowns of resistance training research, interpreted through The DadStrength Method.
No hype. No trends. Just applied physiology.

• RIR Accuracy in Older Adults: What the Research Actually Shows
  Introduction Repetitions in Reserve has become one of the most widely used autoregulation tools in resistance training. The premise is straightforward: estimate how many repetitions you have remaining before failure, and use that number to govern effort, set termination, and volume accumulation across a training week. For men in their 30s and 40s managing full … Läs mer
• Rotator Cuff Tendinopathy Risk Factors in Men Over 40
  Age above 50 carries an odds ratio of 3.31 for rotator cuff tendinopathy. Here is what the evidence actually means for structured strength training.
• Do Long-Length Partials Increase Regional Muscle Growth?
  A randomized trial in trained young men shows greater distal biceps hypertrophy with long-length partial reps versus full ROM, highlighting regional adaptation differences.
• Weekly Training Volume and Muscle Growth: Evidence Review
  In trained men, 12–20 weekly sets produced similar hypertrophy to higher volumes, with limited added benefit beyond that range.
• Training to Failure and Muscle Growth: Systematic Review Evidence
  A meta-analysis found minimal hypertrophy differences between failure and non-failure training protocols, suggesting proximity to failure may matter more than reaching absolute muscular failure.
