Day 31: Resorted to cycling hill

Feeling like I am getting the flu since yesterday so resorted to riding hills on my bicycle instead of skipping. Also first time I haven't been able to complete an exercise. The katana felled my half-way through. 4x25 leg lifts a huge step up and body certainly felt it. Had to do the plank on my knees, but despite feeling like death warmed over I felt that I was listening to my body rather than giving up. Was ready to give up half way through the leg lifts, but since I am determined to work on my abs especially hard, I just fixed on a corner in my mind and went for it, albeit it not at the fastest speed. Looking forward to a better day tomorrow.
