Just done a second fitness test, with the first test numbers first and improvement in percentage:
Push up 18 23 +28%
Squats 29 37 +28%
Plank 1.12 1.36 +21%
Burpees 8 11 +38%
Quite happy! Plank is weaker relative to others showing I need to work on my core, which weakened after my Achilles rupture 7 months ago when I was without exercise for several months.
Will take again at end of quest, but I’m definitely stronger and fitter
