almost failed the 1:30 plank.
My form was terrible throughout

Few weeks from now, sisiw na lang sa'yo 3 minutes.

i'm only participating cuz of mom's challenge so I'm only doing it once a day, but how many times could I do 1 minute planks for maximum benefit aside from the challenge?

You get maximum benefit from toning exercises when you combine them with cardio.

And/or strength training. You don't lose belly fat from toning exercises alone—you'd have to burn it.

I'm not in it for the toning as much as not being weak as fuck lol
