How long can you hold a plank for?

The Guinness World Record is 8 hours 15 minutes 15 second

How far can you toss a caber?

I am in the Larsi Book of Records. 15 seconds

I read that it is a a long, wooden stick that is thrown as a test of strength in traditional sports competitions in Scotland

I'm not unfortunately G.I. Jane, but I workout the plank and I beat my son, I have better time now.  
Maybe it is short time but for me it is a challenge.
Of course it can change...
I wish I could be strong enough to defeat more than one men, but I'm not.
Seriously do you tried thrown the caber?

Yes, I got it verticle but my toss was more like a drop, hahaha.
Oh, the younger days...

I held a downward dog for about a minute today as she tried to take me down a steep hill.
