5×5 Bench Press Calculator
🔍 What is the 5×5 Workout?
The 5×5 training method involves doing 5 sets of 5 reps for compound lifts like the bench press, squat, and deadlift. It’s popular in strength training programs like StrongLifts 5×5 and Starting Strength, and is known for delivering consistent gains over time.
But here’s the kicker: doing 5 sets of 5 reps at your actual 1RM isn’t practical—or safe. That’s why most lifters use a percentage of their 1RM to determine their working weight. The sweet spot for the bench press in a 5×5 setup is around 85% of your 1RM.
✅ What Does This Tool Do?
This calculator automates the process of finding your ideal working weight for a 5×5 bench press workout. Instead of guessing or doing math in your head, simply enter your 1 Rep Max (1RM) and the tool calculates your 85% working weight instantly.
🎯 Key Features:
