I have friends who are fitter than me who have higher resting heart rates, so I would suggest it's not a great indication of fitness by itself.

im thinking this! For time: 50 Box jump, 24 inch box 50 Jumping pull-ups 50 Kettlebell swings, 16kg Walking Lunge, 50 steps 50 Knees to elbows 50 Push press, 20kg 50 Back extensions 50 Wall ball shots, 10kg ball, 10ft 50 Burpees 50 Double unders or 30 clean and jerks for time.... choose weight? 60-70kg??

How do I find out?

86, so yeah I'm massively unfit, but not as unfit as crazymorton! I'll claim the small victories wherever I can

Resting heart rate

The resting heart rate (HRrest) is measured while the subject is at rest but awake, and not having recently exerted himself or herself. The typical resting heart rate in adults is 60–80 beats per minute (bpm).[2] Resting heart rates below 60 bpm may be referred to as bradycardia, while rates above 100 bpm at rest may be called tachycardia.
Fitness training can lead to cardiovascular changes including hypertrophy of the left ventricle and angiogenesis within muscle tissue. This leads to a state known as athletic heart syndrome, as distinct from the pathological enlargements of the ventricles in ventricular hypertrophy. Resting heart rates for athletes can be well below 60, with values of below 40 bpm not unheard of. The cyclist Miguel Indurain had a resting heart rate of 28 bpm.[3]
Average resting heart rate is correlated with age:[4]
