The Squat 1RM
Calculating your one-rep max (1RM) is crucial for programming strength training. It allows you to work at specific percentages of your max intensity without testing a true 1RM, which can be taxing and risky.

Pro Tips
The Epley formula (Weight * (1 + Reps/30)) is most accurate for rep ranges between 3 and 10.
Always use a spotter or safety bars when testing heavy squats.
Proper depth (hip crease below top of knee) ensures valid and consistent results.
