Cardio after a day off

Took yesterday off because I was tired in the morning and was working late into the night. Got up at 4:30 AM today for a task and kept going until 3:30 in the afternoon when I was released for the day. Went to the gym but didn't accomplish much since I am really tired right now. Did 30 min on bike 12.6 km total and then 30 min on elliptical. Avg HR on both was 130.
