The majority of the guys and a couple of the girls were doing them correctly - nose touching the ground, or close to it.
Howver, most of the girls and some (too many) of the guys were barely flexing their arms, ie ~four inches of drop to 'push up' from.
As a 170 lb old guy who can still fit into the clothes he wore in high school and college, am I allowed to 'tsk tsk' at such ?
ps: although, given a couple current health issues, attempting to run 1.5 miles would doubtless kill me ;-)
