The ever popular and deeply informative podcast ‘Fast Talk’, by Velonews, dedicated an entire episode to Xert, speaking with our founder Armando Mastracci about how an athlete’s limits are only truly revealed at their point of failure. Have a listen here.

You are more than your FTP

Though a big ‘FTP’, or Threshold Power, is highly correlated with performance in endurance sports, this metric alone doesn’t tell the whole story of an athlete.
