Progressive overload is a cornerstone of the training process.But an important thing to remember: it doesn’t only mean adding more weight to the barbell or more kilometers to the week. We can progressively overload the body in different ways: - Intensity of the stimulus. Increasing relative intensity: for example, a barbell back squat with submaximal weight performed with an explosive concentric phase. - Density of the stimulus. Increasing exposure to the stimulus within a shorter time window; e.g. double-threshold training methods. - Variability of the stimulus. Targeting the same quality while changing how it’s expressed; e.g. pull development using different grip widths, pull-ups vs chin-ups, etc. Same principle but different levers.
