The 5/3/1 Calculator is a powerful tool designed for athletes and fitness enthusiasts who are following the 5/3/1 strength training program. Created by Jim Wendler, this program focuses on improving strength across four key lifts: squat, bench press, deadlift, and overhead press. The calculator simplifies the process of determining how much weight to lift in each session, making it an essential companion for anyone looking to maximize their training efficiency.
Purpose and Functionality
The primary purpose of the 5/3/1 Calculator is to help users apply the 5/3/1 program’s principles without the need for manual calculations. The program operates on 4-week cycles, each focusing on different intensity and volume, tailored around the user’s one-repetition maximum (1RM). By inputting their 1RM along with the week of the cycle and the lift they’re focusing on, users can quickly determine the weight they should be lifting in each session.
How It Works
The calculator uses a straightforward formula:
Weight = 1RM * Percentage
Based on the week of the program and the lift in question, the calculator applies the appropriate percentage to the user’s 1RM to determine the weight for each set. The percentages vary by week:
- Week 1: 65%, 75%, 85%
- Week 2: 70%, 80%, 90%
- Week 3: 75%, 85%, 95%
- Week 4 (Deload): 40%, 50%, 60%
Step-by-Step Examples
Let’s say your 1RM for the squat is 200kg. Here’s how you would calculate the weights for Week 1:
- Set 1: 200kg×0.65=130kg200kg×0.65=130kg
- Set 2: 200kg×0.75=150kg200kg×0.75=150kg
- Set 3: 200kg×0.85=170kg200kg×0.85=170kg
Simply input your 1RM and the current week into the calculator to get these numbers without doing the math yourself.
