2x500m efforts with Box Jumps, Bosu Balance and Holds and TRX side to side Jumps in the rest period. The first effort was 1.59.5 but I misjudged the time of the exercises because there were three and I missed the start of the 2nd set and did a 2.21.6 on that one. Out of the 15x500m efforts I did I think it was the only one I missed out on getting under 2 min for 500m.
