There’s no secret formula for lifting in your 50s. Keeping things simple still matters. However, certain approaches can save time, lower injury risk, and improve your ability to build muscle without putting unnecessary stress on your joints.
One such approach is the 3-3-3 method, made popular by coach Gary Walker. “You don’t need heavier weights to gain muscle after 50,” Walker explains. “What you need is greater tension applied more intelligently.” He notes that the 3-3-3 method promotes noticeable hypertrophy using joint-friendly loads, making it ideal for older lifters.
What Is the 3-3-3 Method?
Also referred to as the Tricon method, the 3-3-3 system compresses multiple muscle-building stimuli into a single nine-rep set. It combines three explosive reps, three isometric holds, and three slow eccentric reps.
The initial explosive phase targets fast-twitch muscle fibres. The isometric pauses extend time under tension, while the slow eccentrics raise metabolic stress. Together, these elements deliver mechanical tension, control, and fatigue in one efficient sequence.
The end result is a single set that feels comparable to performing three traditional sets, without increasing load and with significantly less joint strain.
Execute the 3-3-3 Set
First 3 reps: Explosive
Lower the weight under control for two to three seconds, then lift it explosively. Focus on speed and intent, not swinging or momentum.
Next 3 reps: Isometric holds
Lower the weight with control, pause during the lift, and hold the position for three to 10 seconds, depending on your strength.
- With dumbbells, Smith machines, or plate-loaded machines, hold at the mid-range.
- With bands or cables, hold at the fully shortened position.
Final 3 reps: Slow and controlled
Lower the weight for a full three seconds, then lift it for another three seconds, using a complete range of motion.
Use the Method Strategically
Avoid applying 3-3-3 to every exercise. Reserve it for movements where you want maximum muscle recruitment and growth. After completing your 3-3-3 sets, finish the workout with conventional programming, such as three sets of eight to 12 reps.

Who Should Use the 3-3-3 Method?
“For men over 50 trying to build muscle, constantly lifting heavier weights isn’t the solution,” Walker says. “That’s why so many stay stuck. Their chest doesn’t grow, their arms don’t change, and their shoulders, elbows, and knees feel worse than ever.”
Walker explains that the real issue with ageing and training isn’t muscle potential, but recovery capacity. While muscles can still grow later in life, joints, connective tissue, and the nervous system recover more slowly. “It’s not that muscle growth stops,” he says. “It’s that people are using the wrong approach.”
The 3-3-3 method addresses this by focusing on tension rather than load, stimulating growth without the constant push toward heavier weights.
Key Benefits of the 3-3-3 Method
“Holding a weight in a static position creates continuous tension without heavy loads,” Walker explains. “This protects the joints while still maximising muscle stimulation.” He adds that isometric work strengthens tendons and ligaments, with research showing static holds can improve tendon stiffness and collagen production over time.
Three Drivers of Hypertrophy in One Set
Walker describes Tricon training as delivering mechanical tension, metabolic stress, and muscle damage in a single set. Explosive reps activate fast-twitch fibres, isometric holds increase time under tension, and slow reps finish with metabolic fatigue. “That’s the full hypertrophy package,” he says, “without unsafe loading.”
Stronger Mind–Muscle Connection
Isometric holds also enhance muscle awareness. “When you hold a weight, you’re forced to feel the muscle working,” Walker notes. “That improved connection helps your nervous system activate the right fibres more effectively in future reps.”
The Bottom Line
No training method works on its own. Whether you use the 3-3-3 method, a 2-2-2 tempo, or traditional lifting, results still depend on fundamentals. That means allowing enough recovery, applying progressive overload over time, and training consistently week after week. Combined with proper nutrition and quality sleep, minimalist approaches like 3-3-3 can help you continue building muscle well into later years.
