Interactive Muscle Map and Exercise Database

ChunkItUp is an exercise-discovery site built around an interactive muscle map. The current public product includes a complete exercise library, muscle targeting data, structured movement guides, and video demonstrations where available.

The muscle heatmap is a visual representation of the human body where you can click on any muscle group to see exercises that target that specific area. The heatmap shows both primary and secondary muscle activation, helping you understand exactly which muscles each exercise works and plan balanced workout routines.

The library includes difficulty labels and many guides offer easier and harder variations. These labels are general references, so choose a version you can control and seek qualified help when you are unsure about pain or technique.

The library includes bodyweight, free-weight, band, and machine movements. Category data is shown separately because the current source taxonomy does not always represent literal equipment.

ChunkItUp does not claim that every database record has been independently reviewed. Exercise pages avoid unsupported medical or performance promises and stay tied to the source muscle-map and technique data.
