I did a lot of awkward object carries (chixsans, 4" iron, 3" iron, plywood boards, etc). I also spent a lot of time tightening and loosening wing nuts with an 8 pound hammer.
Despite all of this, I still felt my hard earned fitness slipping away. The training period has come to an end and I will be starting a schedule with 14 days of work and 14 days off. I will be challenged to make the world my box and get into a rhythm again.
