I didn't have time for the gym this morning so I decided to do two quick circuit workouts that really left me sweaty and worked my whole body.
I started by doing a warm up consisting of airsquats at different tempos for about 3 minutes.
Then I set my timer for 10 minutes and did as many reps as possible of:
20 ab exercises (sit-ups, crunches, mountainclimbers, I varied)
After that I set my timer for 8 minutes and did as many reps as possible of:
15 back raises
21 minutes in total and a complete full body workout.
