What it concludes

• Sam Sulek's triceps receive 25% of his training volume despite triceps making up less than 4% of total body muscle.
• Training the initial range of motion (the stretched position) promotes greater muscle adaptations than training at the end of the range.
• Controlled negatives and progressive overload are essential for maximizing muscle hypertrophy and avoiding training plateaus.
• A body-part training split ("bro split") can lead to disproportionate volume between upper and lower body muscles.
• Training to failure 96% of the time is excessive and can lead to recovery issues for most people.
• Sam Sulek earns a B grade overall for his training regimen, excelling in effort and consistency while suffering from suboptimal split structure and excessive failure volume.
