Too many circuits....

For the last year or so Gary and I have been going to Parkwood Gym (to get some muscles) and twice a week on Tuesdays/Thursdays we go to a circuit training class at 7am (ouch). Normally, running in the evening is perfectly possible after morning circuits and I am sure the benefits of varying training and building up strength are very much worth it! However, this morning was a whole different kettle of fish! The instructor is leaving so he decided to give us a final class we weren't going to forget. So I spent the first hour of Valentine's day punching my husband as well as doing all sorts of situps, push ups, lunges, squats, step ups and squats (repeatedly). I am 110% exhausted...
