1. Really want a challenge.
2. You think it can't be that bad.
3. You have a screw loose.
100 Sandbag Overhead Press in as few sets as possible - 100 Skip penalty everytime you drop the bag below chest height.
Follow this immediately with 200 Sandbag Back Squats - 20 Press Ups each time you need to rest.
Complete the whole session with a running clock.
Men aim for a 40 kg sandbag; women aim for 20kg.
Train very hard!
