1. Getting hurt/injured - like right now sitting at home limping around with the leg wrapped up like a mummy. You take the usual precautions with form and not ego lifting in the gym but sometimes shit happens that is beyond your control. Take a deep breath and realise its only a minor setback and use that as motivation to work even harder when I can literally set foot in the gym again. I know I am itching to go back thats for sure.
2. Not getting enough sleep - this one annoys the shit out of me. After a deadlift session all you want to do is have a nice bout of shut eye to maximise the recovery process but when the body/friends/phone have other ideas that can fly out of the window real quick! Always have a backup plan ready in situations like this. I wouldn't know how I would be able to deal with this without my sleep toolkit that knocks me out faster than georgie foreman damnit.
3. Mobility - I have always had tight muscles and tendons so this took a fair bit of work. Learned heaps from mobilityWOD, equipped myself with rumble roller, lacrosse balls, PVC pipes and stretch bands, then went to town every day for months on end contorting myself into a pretzel until I kneaded and pulled my body into submission. It still takes daily effort to maintain and work on bits that I have neglected. The first time I could touch my toes I had tears of joy (and pain) flood my eyes!
