Tottenham stars Dele Alli and Harry Kane were back at their Enfield training base on Friday as a host of the club's biggest stars underwent fitness tests following their summer breaks.
France internationals Hugo Lloris and Moussa Sissoko were also present to test their reactions, flexibility and core strength ahead of the new Premier League season, which kicks off in just under a month.
There was also a grueling Vo2 Max test to complete, which involves running to exhaustion on a treadmill while your oxygen intake is measured. It is widely regarded to be one of the more unpleasant parts of elite-level fitness.
