Samsung says No,
it says, what matters is the "length of time" spent on top of the gym floor rather than, how many Push-ups one did or performed
So it doesn't reward or say, well done you did 10 Push-ups more than your previous best, rather says you did 5 minutes more
Who actually designed this activity app on the watch because there is no place to add How many Push-ups one did.
Bit of an update
