# One Rep Max Calculator

### 1 Rep Max

Your max strength for one repetition.

### Strength Progress

Track your 1RM to monitor gains.

### Training Safety

Warm-up before heavy lifting.

One Rep Max Calculator: Elevate your weightlifting routine! Effortlessly estimate your 1RM and monitor strength gains with our easy-to-use tool.

## Features of One Rep Max Calculator

**User Inputs**:**Weight Lifted**: The amount of weight the user lifted.**Number of Reps**: The number of repetitions performed with that weight.

**Calculation Formulas**: The calculator uses three popular formulas to estimate the 1RM:**Epley Formula**: 1RM=Weight×(1+Reps30)1RM = \text{Weight} \times (1 + \frac{\text{Reps}}{30})1RM=Weight×(1+30Reps)**Brzycki Formula**: 1RM=Weight×(3637−Reps)1RM = \text{Weight} \times \left(\frac{36}{37 – \text{Reps}}\right)1RM=Weight×(37−Reps36)**Lander Formula**: 1RM=100×Weight101.3−2.67123×Reps1RM = \frac{100 \times \text{Weight}}{101.3 – 2.67123 \times \text{Reps}}1RM=101.3−2.67123×Reps100×Weight

**Infographic Section**: Highlights the importance of tracking 1RM, monitoring strength gains, and ensuring safety while lifting.

### How It Works:

- The user enters the weight lifted and the number of reps.
- The calculator computes the estimated 1RM using three different formulas (Epley, Brzycki, Lander).
- The results are displayed at the bottom of the page, showing the estimated 1RM values from each formula.

This tool helps weightlifters track their strength progress by estimating their 1RM based on submaximal lifts.
