order to customise strength-building work for each muscle group. The maximal load is the load which can be lifted once. This is determined by: • apparatus measuring muscular performance, • direct method: – lifting weights until failure, • indirect method: – the subject lifts a weight that is close to the maximal load several times, – the value of the load and the number of repetitions are noted, – the maximum load is calculated using:
