Aerobic with 5 x 3 mins "intervals" in the middle. I just can't get my legs moving fast enough these days to really get the chest bursting. I think I'm going to switch Tuesday's 15x15s to some short actual intervals (maybe even on the track, which I checked on yesterday and seems pretty cool). Also going to go sort out gym stuff early next week (was going to do it today but Membership services closes too early. Boo.
