Gym and weight loss calculators
Three small tools that answer the questions beginners ask most.
- Weight loss pace calculatorEnter your weight, goal and target date to see the kg per week you need and whether that pace is realistic.
- Gym membership break-evenWork out how many gym visits it takes for a membership to be cheaper than day passes, and how often you need to go.
- One-rep max calculatorEstimate your one-rep max from a lift you can do for several reps, with a table of training weights from 50 to 95 percent.
