1 RM Print E-mail
The 1 RM calculator allows you to calculator your maximal strength in a given exercise based on the number of repetitions you can can perform with a submaximal load.

Instructions:
1. Pick a weight you can maximally lift 2-12 times.
2. Lift it for as many repetitions possible and enter weight and number of repetitions.
3. The top panel shows the estimated RM-values. 1 RM is the maximal weight you can lift 1 time. 2 RM is the maximal weight that can be lifted 2 times, etc.

Stephen:it does not say "pick up a weight", it says"pick a wieght".Any exercise goes. if you can, say, lift 200 lbs. 4 times, put those numbers into the calculatorand it will tell you how many lbs. you can lift 1,2,3,5times and so on.

I don't fully understand this test. I'm a cricket coach and I am using these tests on my (currently) woefully unfit cricketers.
When you say pick up a weight what exactly do you mean? Pick it up from the floor and shoulder press it? And should I have to change the weight depending on the existing strength of the cricketer?
I only want a minimum of equipment hence bleep test, cooper run, step test, pressup test, and body composition tests all working well.
Fantastic website by the way.
