6-Day Hypertrophy Split Goes Viral

A 6-day hypertrophy split, like the one that has gained significant attention, is a demanding training schedule that can lead to substantial muscle growth by increasing the training frequency for different body parts. This type of routine is generally considered an advanced approach, best suited for individuals with a solid foundation in strength training who can handle the high-volume workload and have adequate time for recovery. The program's structure, a hybrid of "Push/Pull/Legs" and "Upper/Lower" splits, allows for each muscle group to be trained multiple times a week, a key factor for stimulating muscle growth. The initial three days focus on pushing movements (chest, shoulders, triceps), pulling movements (back, biceps), and legs, followed by two days dedicated to the entire upper and lower body, respectively. A core component of this viral plan is the use of "Reps in Reserve" (RIR) to guide intensity. RIR is a method of autoregulation where a lifter gauges how many more repetitions they could have completed with good form at the end of a set. For hypertrophy, a target of 1-2 RIR is often recommended, meaning the lifter is working close to muscular failure without the heightened risk of overtraining that can come with pushing to complete failure on every set. The emphasis on machine-based exercises like lat pulldowns and leg presses offers distinct advantages for muscle growth. Machines provide stability, which allows the lifter to focus on isolating and applying maximum tension to the target muscle. This can be particularly beneficial for hypertrophy, as it helps to ensure that the intended muscle is the primary mover throughout the exercise. The mentioned personal bests of a 160kg (352 lbs) bench press for 5 repetitions, a 300kg (661 lbs) deadlift for 2, and a 200kg (440 lbs) squat for 4 are highly impressive for a recreational lifter. A 300kg deadlift, in particular, is an outstanding lift that few people ever achieve, often considered an elite-level lift depending on body weight. For an average male with a few years of consistent training, a deadlift of 1.5 to 2 times their body weight is a solid benchmark, making a 300kg pull a significant feat of strength.
