Body Balance is designed to measure your overall body structural parity. The percentages provided are derived from a T-Nation article that provides anecdotal and observational data on a number of different exercises. This data is used in Body Balance to determine expected lift weights derived from a single base exercise. The base exercises include the Deadlift, Back Squat, Bench Press, Front Squat, Close-grip Bench Press, Barbell Curl, Dumbbell Curl, and Dumbbell Overhead Triceps Extension. Additional exercises range across a number of muscle groups.
Body Balance now features a quick and easy RM calculator! You can calculate any rep max range from 1-12, based on an existing weight and rep range you already know. It allows you to use any of the most popular formulas. The application has also been updated for copy paste functionality app-wide. Long press a weight set value to paste into it directly. There's also a lb-kg calculator in case you need one.
Once you choose your base exercise and input a weight for the lift, Body Balance will give you expected lift weights for some other exercises. You can input your actual numbers to determine muscle groups that may be lagging. The numbers are for a given rep range, so if you input a number for a 5RM as the base exercise, the expected values correspond to 5RM numbers.
Body Balance supports Imperial and Metric units.
NOTE: Body Balance is NOT designed to estimate what you should be lifting and should NOT be used for this purpose. It is strictly for your existing lift numbers. Do NOT use it to estimate numbers for new exercises. Please be smart about your weightlifting!
