How I built 16.5 inch arms (with bad genetics)

His tricep training is similar: six total hard sets per week, 4-8 reps, taken to failure (RP10), in addition to pressing movements. He uses single-arm tricep pushdowns and the Smith machine JM press, focusing on progressive overload. He switched from overhead extensions due to loading difficulties and shoulder comfort.

The creator discusses his personal struggle with growing his arms, starting at 12 inches and reaching 16.5 inches at 11% body fat. He explains that his long arms made it harder to fill out, and he debunks the myth of needing excessive volume, promising a faster, more effective method without the common mistakes.

He outlines key errors, including focusing on the 'pump, burn, and squeeze' instead of mechanical tension and proximity to failure. He clarifies that muscle growth comes from mechanical tension and training close to failure, not just feeling a pump. He also highlights doing excessive volume and not training hard enough with heavy enough weights.

The video explains that muscle growth is primarily driven by mechanical tension (the stretching/pulling force on the muscle) and training close to failure. This recruits larger muscle fibers capable of significant growth. Progressive overload, continuously lifting more weight over time, is crucial for sustained progress.

The creator advises against excessive volume (e.g., 15-20 sets per week per muscle group), stating it degrades quality and leads to diminishing returns. He suggests around 10 direct sets per week for arms, capping at about five hard sets per session, acknowledging overlap from compound exercises.

He stresses the importance of training to genuine failure, meaning the final reps are extremely slow and grindy due to involuntary slowdown. He clarifies that 'Reps in Reserve' (RIR) is an objective measure of how many reps are left, not subjective difficulty. Many people stop too early, leaving potential growth on the table.

The video emphasizes that getting stronger is fundamental for arm growth. He argues that if you're not lifting more weight for the same reps over time, your arms likely aren't growing, regardless of pump or mind-muscle connection. He tracks every set and rep to ensure progressive overload.

He details his minimal but effective bicep routine: six total hard sets per week, 5-8 reps, all taken to absolute failure (RP10). He trains biceps on two different days using a push-pull-legs split. Exercises include machine preacher curls and supported incline dumbbell curls, focusing on adding weight or reps over time.

The creator explains why he opts for lower rep ranges (5-8 reps) for biceps and triceps. He believes it maximizes mechanical tension and allows for training closer to true failure compared to higher rep sets, which are longer and accumulate more waste products, making it harder to push to actual failure.

Key tips include: less is more, incorporating exercises that train muscles in both shortened and lengthened positions (e.g., preacher curls for shortened biceps, incline curls for lengthened), and consistently training to absolute failure for all arm work to ensure maximum effort and muscle fiber recruitment. He also recommends taking regular measurements (e.g., monthly) to objectively track progress.

He lists his favorite arm exercises, chosen for stability, ease of progressive overload, being pain-free, and targeting the muscle effectively. For biceps: preacher curl machine, single-arm dumbbell preacher curl, supported incline dumbbell curls, dumbbell hammer curls, and seated alternating dumbbell curls. For triceps: single-arm tricep pushdowns, Smith machine JM press, chest press machine tricep extension, dip machine, overhead tricep extensions, and dumbbell skull crushers (allowing humerus movement for stretch).

The creator concludes by reiterating that if he, with his 'bad genetics', can build substantial arm size by applying these principles, anyone can. He emphasizes focusing on an optimized program, progressive overload, and training to failure, rather than chasing the pump or burn. He also promotes his coaching services for personalized strength and bodybuilding programs.
