Features of 1RM Calculator

  1. User Inputs:
    • Weight Lifted: The weight the user lifted during their exercise (in kg)
    • Number of Reps: The number of repetitions the user completed.
  2. 1RM Calculation:
    • Uses the Epley formula: 1RM=weight×(1+reps30)\text{1RM} = \text{weight} \times \left(1 + \frac{\text{reps}}{30}\right)1RM=weight×(1+30reps​).
    • The formula estimates the maximum weight the user can lift for a single repetition based on the weight and number of reps performed.

How It Works:

  1. The user inputs the weight they lifted and the number of repetitions.
  2. When the "Calculate 1RM" button is pressed, the calculator computes the user's one-rep max using the Epley formula.
  3. The result is displayed, giving the user an estimate of their 1RM.

This tool is useful for athletes and gym-goers to measure their strength and progress over time.
