United StatesWhether you're a competitive lifter or just want to improve your strength and fitness, your one-rep max (1RM) is an essential tool. Calculate your max safely and easily, and then track it over time, on any lift with our easy-to-use calculator!
In the simplest terms, your 1RM is the amount of weight you can lift for one rep on any given lift. In general, it’s good to know your max for key lifts like the squat, bench press, and deadlift, but your 1RM is critical even if you never plan to train that heavy.
Many lifting programs are designed with a percent of your rep max in mind, and may call for something like using 65% of your 1RM for a given exercise. When you see that, you have to either test for your 1RM or estimate it. Testing your 1RM can be pretty intense, and it requires a high degree of caution to avoid injury.
Fortunately, you can estimate your 1RM without testing it! Exercise scientists have devised a formula that's fairly accurate for most people, which is what powers this calculator. Our calculator makes it easy to calculate and track your 1RM and multiple percentages of it for every lift in the book!
Features:
• Calculate your 1RM and percentages
• Choose from a variety of lifts (deadlift, bench press, squat, etc.), or add your own
• Track and chart your 1RM history for each type of lift
• Add notes each time you calculate your 1RM
• Improve your weight training with articles by Bodybuilding.com experts
• Choose imperial or metric system
• Incredibly easy to use!
Beautiful design with really elegant graphics my only criticism is that I wish there was an option for the date to be changed from MM/DD/YYYY to DD/MM/YYYY
Good app, but room for improvement It's kinda silly that it doesn't give you the option to use weight measured in Kg, which is the standard measurement for weight in half of the world. If I have to go find another calculator to use this calculator. Also, I've got trouble understanding why you can't add decimals like 150,5, since the small improvements are important in powerlifting. But I like that you can save your stats, and it's easy to use and navigate.
Doesn't show decline bench press.
Nice app, it's easy to use and has an attractive interface. i would like to see an option to use other 1 rep formulas. it seems like a relatively simple modification, which would make the app much more useful, as well as fun to play with.
Kind of silly that it only shows you 70% and up for your one-rep max most Program start at 30% please fix this
Perfect.
It guess it does what it's supposed to, but when it calculates your percentages, it doesn't go below 70%! The free version on their website goes down further than that. Also, once you log the 1RM, you can't view the percentages, which is silly.
