Why Arnold's Workout Routine Defied What Scientists Thought

The Arnold Schwarzenegger workout routine hit gyms like a bombshell in the 1970s. Bodybuilders saw a man training twice daily six days straight. They watched him perform 20 to 30 sets per muscle group weekly. The volume changed the sport forever.

How the Arnold Schwarzenegger Workout Routine Builds Muscle Through Volume

Arnold followed six weekly workouts with multiple exercises per muscle group and plenty of training sets because he believed in high-volume training for optimal muscle growth. His approach featured 4 to 5 exercises per muscle group with 5 sets of 10 reps each. Volume gets calculated by multiplying sets, reps, and weight together. Schwarzenegger typically followed 4 to 6 sets per exercise with 6 to 12 reps per set to focus on both strength and hypertrophy.

Arnold Schwarzenegger’s volume training routine represents an extreme high-volume bodybuilding template from a specific era. He performed 20 to 30 plus sets per large muscle group per week in peak bodybuilding phases. Some accounts describe even higher numbers.

The sheer amount of work separates this approach from modern standards. He routinely trained for several hours daily, often splitting his workouts and training twice a day. Schwarzenegger trained twice a day six days a week and spent up to five hours daily at the gym.

The Six-Day Split Behind the Arnold Schwarzenegger Workout Routine

The Arnold workout split is a six-day routine designed to train the significant muscles like arms, legs, forearms, calves, shoulders, back, and chest two times a week. The Arnold split workout plan consists of three training sessions repeated twice for a total of six sessions in a week. Arnold trained each muscle group twice a week using Sundays for rest.

Schwarzenegger had a twice-a-day training split where he typically trained his chest, abs, and back in the morning and targeted his arms and shoulders in the evening, with legs on separate days. For his pre-contest workout Arnold often split his routine in half every day because it allowed him to perform antagonistic supersets and alternate between opposing muscle groups.

The Arnold workout split allows lifters to train all muscle groups the recommended two times per week, promoting muscle growth and superior strength gains. The frequency separates amateurs from serious competitors. Schwarzenegger’s Level 1 Exercise Program is a six-day body part double split consisting of nine individual workouts spread across the week with one dedicated rest day.

The Mental Approach That Powers the Arnold Schwarzenegger Workout Routine

Arnold often spoke about the mind-muscle connection emphasizing the importance of actually feeling each rep instead of merely going through the motions, which was crucial for optimizing muscle growth. He treats the mind-muscle connection as a skill to be developed, not a passive byproduct of lifting, saying if your mind is involved in your workout there is no way you can lose.

When he trained Arnold concentrated with 100 percent focus which allowed him to reach even greater intensity levels. Arnold was a big believer in going 100 percent on all reps of all sets and often commented about people who focus too much on the workload ahead making it easy on early sets to save energy.

The psychological component matters as much as the physical work. His philosophy was rooted in pushing the limits of physical and mental endurance believing in the power of visualization and a positive mindset to achieve goals, which was a critical component of his success. Mental strength dictates whether you complete the final rep.

Shocking the Muscle in the Arnold Schwarzenegger Workout Routine

Arnold championed the concept of shocking the muscle, a strategy of constantly varying exercises, sets, reps, and weights to prevent adaptive resistance and keep the muscles guessing and growing. When a workout routine becomes too familiar muscles no longer experience the same level of challenge leading to a strength plateau and stalled hypertrophy, so Schwarzenegger believed constantly varying routines, exercises, reps, and intensity would shock muscles into growth by forcing them to adapt to unfamiliar demands and triggering new muscle fiber recruitment patterns that traditional progressive overload alone might miss.

Within a basic framework Arnold constantly changed his exercises because he liked to shock the muscles by not letting them get complacent in a constant routine, and if he found an exercise was no longer producing gains he’d switch it for another. Shocking meant doing things like stripping by starting at the heavy end of the dumbbell rack and dropping from each weight with no rest, making 40 pounds feel like 110 pounds and making the muscles grow because he had given them the shock they desperately wanted.

This approach prevents stagnation. Muscles adapt to stress patterns quickly. Changing exercise order, rep schemes, and intensity breaks adaptation cycles. The body has no choice but to respond.

Recovery and Rest Days in the Arnold Schwarzenegger Workout Routine

Arnold Schwarzenegger did take rest days during his bodybuilding career and most of his workout routines involve going to the gym six days a week, sometimes twice a day, with a rest day on Sunday. Arnold typically trained six days per week during his competitive years taking one full rest day. The single day off allowed his body to rebuild.

Arnold’s rapid recovery stemmed from prioritizing eight hours of quality sleep nightly to maximize growth hormone release and muscle repair, consuming multiple protein-rich whole food meals throughout the day, and implementing strategic training splits that allowed adequate rest between muscle groups whilst incorporating active recovery techniques including stretching and posing practice. Sleep and nutrition mattered as much as training intensity.

Research suggests that 3 to 5 minutes is the ideal amount of rest for multi-joint exercises like squats. Arnold explained that strength and muscle correlates with fatigue and intensity, so going close to failure maximizes results from each set but generates fatigue leading to longer rest periods, and you’re leaving results on the table if you don’t rest long enough while training till failure.

Exercise Selection in the Arnold Schwarzenegger Workout Routine

One common mistake people make when trying to follow this training split is using isolation exercises, but while Arnold did do them the Arnold split focuses on using basic compound exercises like the barbell bench press and squats. The routine focuses on compound exercises like squats, deadlifts, bench press, and pull-ups but also includes isolation exercises for complete muscle development.

Arnold trains in a pyramid rep scheme starting at 12 reps and working down to 6 as weight increases across sets, supersets chest exercises directly with back movements to maximize workout density and keep the pump constant, with the flat barbell bench press anchoring every chest session. The pairing of opposing muscle groups saved time and increased intensity.

Arnold performed exercises with an exaggerated range of motion because he believed it led to superior gains and helped him keep his muscles limber. Full range of motion taxes muscles through complete contraction and extension patterns. Partial reps leave gains on the table.

Who Should Follow the Arnold Schwarzenegger Workout Routine

You should probably steer clear of running Schwarzenegger’s workout split if taking your first fitness steps because this is an extremely high-volume demanding exercise routine requiring mastery over many different exercises, equipment, and movement patterns, and for a bodybuilding newbie it is more than overkill so your best bet is to start with a beginner routine first. Such a voluminous training approach is not recommended for beginner or even intermediate lifters.

The program demands years of training foundation. Your connective tissues need adaptation time. Your work capacity must support hours of daily training. Recovery ability separates who can handle this volume from who cannot.

Six days a week high volume training is best saved for when you are truly ready, and novice lifters or those just getting back into the groove can simply run the same routine with a rest day or two between each main session. Start with three or four training days weekly. Build up gradually over months.
