Open calculatorGet a better read on your machine strength
Use the calculator that matches the machine in your gym. That gives you a much more useful answer than comparing numbers from completely different machines.
Pick the exercise you did
Leg press, hack squat, leg extension, leg curl, and calf raise results are not interchangeable. Start with the movement you actually performed.
Match your machine
A 45-degree sled, horizontal press, vertical press, and Smith-machine setup can give very different numbers. Pick the closest match.
Keep your setup consistent
Seat position, foot placement, range of motion, and reps can change your result. Keep those details similar when you test again.
Enter the weight correctly
Some machines use the plates you add; others use the stack or the machine’s listed weight. Follow the prompt on the calculator.
