Technically, isometric testing is not a true repetition maximum assessment, but it is similar enough to merit inclusion in this guide. Several researchers and practitioners have used barbell velocity to estimate the potential maximal strength of an exercise, but conflicting results have made this practice controversial. Estimated Max Testsĭue to the perceived risk, technical breakdown, and residual fatigue of single-repetition maximum testing, submaximal testing is often performed with multiple reps and calculations. Additional tests to local muscle groups or specific joints are common in both the medical and performance environments. Isolated Strength TestsĪ single joint or muscle is commonly tested, such as hamstring tests and adduction of the hip. Due to the fact that the primary purpose of one-repetition maximum is to find the highest load an athlete can handle, technical limits and instrumentation are part of the testing process to ensure safety and appropriate load scoring. The weight lifts-specifically the snatch, clean, and jerk-and, at times, loaded jumps, are used with athletes. While barbell testing is commonly preferred, machines are also options in some circumstances. The most popular tests are conventional strength exercises such as the bench press, barbell squat, and deadlift. Recently, 1RM testing has also begun including split squats and other exercises. Less frequently used are pulling and other motions that use the upper body only. The grey area between field testing and laboratory-grade evaluation is thinning because of access to technology and education thus, the quality of data collected from coaches is improving. The reliability of one-repetition maximum is very high with advanced trainees, but when equipment and protocols are adjusted, less-experienced athletes can be assessed as well. The degree of skill and technique necessary to perform maximum testing varies depending on the exercise used and the equipment selected. The same program that asked you to do your 3RM and 5RM could alternately have said to do 93% 1RM and 87% 1RM, respectively.Maximum strength and power testing in the field is relatively safe and easy to assess, and correlates well with sports performance and other training modalities. Your 5RM would be 305 x 0.87, giving you a working weight of roughly 265 pounds. To find your 3RM, note that 3 corresponds to 93% 1RM, so multiply 305 x 0.93, which estimates your working weight to be 285 (rounded up) pounds. Start by computing your 1RM just divide 245 pounds by 0.80, which estimates your single-rep max to be 306.25, which can be rounded down to 305. If you can just do 8 reps with good form, look at the chart and see that 8 means you’re working at 80% of your 1RM (80% 1RM). Say you know you can do 245 pounds for a clean set of 8 reps, but you don’t know your one-rep max. Let’s say your strength workout calls for you to use your 3RM and 5RM for sets of front squats. You’ll need the table below to essentially do the conversion in a different way. What’s different here is that instead of a giving you a percentage of your one-rep max, you’ll see 3RM, which indicates you should use a weight that you can do for three and only three reps. Some programs are set up a little differently and will instead tell you to do your 3RM, 6RM, or some other number. For instance, if you want to do 85% 1RM, the calculator tells you to use 255 pounds (which is simply 0.85 x 300). The calculator gives you all the relevant loads, which are done simply by multiplying the percentage by your 1RM (in this case, 300 pounds). Strength coaches set up programs with percentages based on your 1RM because they don’t know your actual strength level, but they know what percentages they want you to be using relative to your single-rep max. It’ll show your estimated 1RM to be 300 pounds. Let’s try it for the row, assuming you can do 225 pounds for 10 reps. The calculator estimates your one-rep max based on the amount of weight you can lift on a given move, and the number of clean reps you can achieve before muscle failure. Based on that we can estimate not just your one rep max (100% of your 1RM), but other loads as well: your 85% 1RM, 70% 1RM, or 55% 1RM, depending on what your program calls for. Let’s say you know you can lift 225 pounds for 10 reps-and only 10 reps, with good form-on the bent-over row.
