My heart was racing and I was sweating through this workout!
If you are able to, do 10-20 minutes of cardio then follow with the "Morning Circuit." The 10 second breaks between each move are great for a half-awake state, but that doesn't mean the circuit is easy!
I used a repeating interval timer (Gymboss) and set it to 30 rounds of 20 seconds work and 10 seconds rest. You can also use a stopwatch/phone ap/internet.
