10 minutes?????!!!!!! Tell me this is some sort of time lapse photography thing!

nope, no timelapse. no edits either. just a man and his will.
lol i do it shirtless when im alone, cos heat dissipates better, but im camera shy so i wont get half naked for steemians lol. maybe in future...
my personal best is 15 mins. focusing on breathing. is a major key. it allows the body not to get too exhausted. and overheated.
but a person really dont need to go above 3 mins for the benefits of a plank. heck even two mins is all it takes. next step is to do it with a little weights.

i spent cold winter nights training just to keep warm. lol.

but to be able to do it longer. one does need to train his lower back. and posture. in a certain way. so that the form would not break down.
if you really wanna test your ab strength and lower back strength then do this and see how long you can last
1 lie down on back flat as possible.
2 lie so that you would not have free space between lower back and ground.
3 raise both legs straightened at 45angle. keep them.
4 while maintaining your lower back in contact with the ground.
time it.

most people cant withstand even 30 secs like that. cos its so darn hard. and the weak lower back spine muscles shows themselves.
i remember how i started to do this exercise to strenghten my lower back.
i did it with one leg at a time. untill i could do it with both legs.
cheers.

Right off the first rip. Dang homie!!! I will be checking your entry out shortly. hehe <333
