Michael and Christian Gaiera engage in high-volume arm training.
High-volume training involves performing numerous sets and reps targeting specific or various muscle groups. Research indicates this approach can lead to muscle hypertrophy and enhanced skeletal and muscular strength (1). The Tren Twins, Christian and Michael Gaiera, exemplify this training method through intense, high-volume workouts, especially for arm day.
This article delves into the Tren Twins‘ workout regimen, offering a comprehensive overview of their training routines. It also highlights their specific dietary practices and how they contribute to their remarkable muscular development.
About The Tren Twins

Born on April 2, 2001, in Michigan, these brothers spent much of their childhood in foster care due to their mother’s struggles with alcohol addiction and abuse.

Christian and Michael have gained recognition through hard work and dedication, partly for their distinctive bodybuilding techniques and impressive physiques.

The Tren Twins’ Upper Body Workout Program
Christian and Michael Gaiera have made it known that they use Trenbolone or Tren (where they got their name). Trenbolone is a steroid some bodybuilders use to help with muscle growth and appetite. Studies have shown that anabolic steroids can enhance appearance by building muscle mass and lowering the damage that happens to muscles during a hard workout (2). However, we aren’t suggesting steroid use, and it’s imperative to know their side effects and to seek the guidance of a health professional before taking them.
The Tren Twins both do a five-day split workout program, as they have a separate workout program for their upper bodies. Here’s an outline of Christian and Michael Gaiera’s workout split.
