A3 Repetition max 1RM


For muscular strength training we need another way to measure intensity.


1RM is called the one repetition max. It is the heaviest weight a person can lift for just one time. 1RM is measured in kilograms (kg). 1RM is 100% intensity for muscular strength.


Once we know the 1RM weight we can work out what weights are needed to work at a lower intensity for muscular strength:


Weight they should lift = 1RM × intensity


Intro


Discuss which exercise for which you are likely to have the highest 1RM


For example, Elina’s 1RM for a bench press is 60kg.


To work at 70% intensity for muscular strength:


Weight she should lift = 60 × 70/100 = 42kg To work at 85% intensity: Weight she should lift = 60 × 85/100 = 51 kg


132


Muscular strength training uses high intensity and low repetitions.
