Peter's beginner programming template is built for a specific profile he encounters frequently: someone with good cardiovascular fitness but essentially no resistance training background — often a woman who has run or cycled for years but never touched weights. Given six hours per week of training time, he splits it evenly: three hours of cardio maintained at existing levels, three hours of structured resistance training. Three one-hour full-body sessions (Monday/Wednesday/Friday or Tuesday/Thursday/Saturday) provide sufficient frequency for skill acquisition and stimulus without overwhelming recovery capacity. The weekly volume target is 10–20 sets per body part, distributed across the three sessions, with 3–4 sets per exercise at 6–15 reps and 90–120 seconds of rest. Supersets — pairing opposing muscles like chest and back, or biceps and triceps — make the hour highly efficient while still providing adequate rest for each muscle group. Crucially, intensity starts conservative at 3–4 RIR for the first weeks and progressively tightens toward 1–2 RIR as movement quality and body awareness develop. This population, Peter notes, is tremendously rewarding to work with because the gains in the first year of training can be remarkable.
Testosterone accelerates muscle growth; chronic cortisol destroys it. Poor sleep blocks recovery and rebuilding. Consistency compounds over time — and one great training month means nothing if the next is inconsistent. The gym is only half the equation.
