Finding your 1rm and 5rm?
Heya guys, I need to find out my 1rm and 5rm for a few exercises, aside from loading up weight till you can only lift it 1 or 5 times (and probably wasting some energy on reps that weren't quite on the mark, And I really dont want to load up and squat that heavy) is there some formula or online calculator or something that will let you plug in a certain amount of weight you lifted along with the reps and have it convert those values into your 1rm and 5rm?
And if so, is there a good rep range to aim fo when doing them (some try to use a weight your pretty sure you can do atleast 8-15 times or something, like is it more accurate when you stick to lower reps or higher reps, and I assume partial reps dont count, but if they dont, wouldn't that make lower reps less accurate for that?)
Thanks :D
