ELXR is a fitness mobile application that provides a DNA-based training programme. It does so by analysing a user’s fitness at a genetic level. This analysis is obtained from a DNA test kit on the ACTN-3 gene and results from nine fitness modality assessments. These assessments measure the user’s aerobic capacity, anaerobic capacity, agility, balance, endurance, flexibility, power, strength and speed. The results will determine the user’s fitness level and incorporate the DNA results to generate their personalised programme.
