id say figure out what 80 percent of your max is
say you go to the rack and pick up a 60 pound kettlebell would you say thats too much
kind of dial your max in

i do the following

25 yards at 60
35 yards at 70
45 yards at 80

Navem nu, cuando sol
Tutu nu, vondo nos nu
Vita em, no continous non
Nos nu ekta nos sepe ta, amen

When the sun shades the ship
We sweat and life is not safe
To swim or to touch not
When we unite we hedge amen
