Think big to small: Research shows that starting your workout with compound lifts (bench press, squat, overhead press, etc.) followed by smaller isolation movements leads to a greater anabolic response.
Get in, get out: Try to shorten your workouts without decreasing overall volume. Testosterone levels are higher after shorter workouts (less than 60 minutes) that keep rest periods brief (30-90 seconds), like this short but intense workout from Craig Capurso.
Keep more weapons in your arsenal: Utilizing lifting methods like forced reps, negatives, and dropsets will help keep intensity and testosterone high!
