1 Rep Max Calculator
1RM is a must have for any Bodybuilder, Fitness Fanatic, or Gym Jockey. Using popular formulas, it can accurately estimate your 1 Rep Max for Bench Press, Squats, Deadlift, or any other exercise in your workout routine. It works for barbells and dumbbells.
It works by estimating with data you already know. You enter the reps and weight you were previously able to successfully complete and it will estimate your 1 rep max!
This app helps keep you safe by giving you an estimate on how much you can lift before actually attempting it yourself. This helps to prevent muscle and body damage so you can keep your health and continue to build your strength.
1RM also has a percentage chart for those who are doing workouts which require knowing the percentage of your 1 rep max.
This app works best when the reps used are less than 12. I recommend using the reps between 3 and 10 for highest accuracy. For this reason, I recommend you do not use this to calculate maxes for exercises such as push ups sit ups or crunches.
1RM will undoubtedly supplement any bodybuilders lifting regimen and can help you achieve more effect sets so you can build more muscle.
ALWAYS USE A SPOTTER. APPLICATIONS LIKE THIS ARE DESIGNED TO MAKE WEIGHT LIFTING SAFER BUT CANNOT GUARANTEE YOUR NOR ANYONE ELSE'S SAFETY. THESE CALCULATIONS ARE ONLY ESTIMATES AND CAN BE INACCURATE.

The app is consistent and accurate as long as you stay within the 12 rep range. Great for building a workout based on your max. You also dont have to max as often because the app can give you an accurate estimation based on your rep ranges with a given weight. It's a useful tool.
Skeptical, but after trying it for a while I found it to be pretty spot on for me and having percentages handy helps, too. A full log would take it to the next level.
Big help calculating my starting weights for lifts in different programs.
great way to quickly calculate where, in theory, you should be. leaves the rest of the energy to getting to the work
Great app, the biggest issue I had with it has been added as a featuren
love the graph showing the increase of the max RM as I progress. should say though that these are obviously estimated numbers and anyone should take the number as a rough guide not gospel. besides that, it does show your progress as you're able to lift the same weight for more reps it will result in an increased 1rm.
This app helps me a lot with planning my short term and long term goals for bodybuilding by helping me figure out what my one rep max is, based on my current weight usage is, and the reps i can do. I can then exteapolate from this to do always keep my workouts intense and invigorating! Thanks for helping me meet my goals and always push myself, @Developers!
Simple and useful one rep max calculator. I dig the Dark theme, and paid for the pro version to support the dev and remove ads.
Absolutely it gives you a reasonable estimation and provides nothing but motivation to achieve that goal or greater. Phenominal App
One of the most accurate calculators out there . Even when you plug in reps above 12 it still is pretty accurate .
they want you to constantly upgrade but if the upgrade is as garbage as the basic app why would I waste my money.
I love this app and recommend it to everyone that I can.
Best RM calculator i found. Does. Everything you need to. No funny business or payment demands.
easy to use just realised your can customise decimal places and increments. essential
Ive been lifting for years. Based on my experienc this app is a pretty accurate guide.
easy to use & navigate... recommend for the experienced and beginners!
