Chair Circuit (set an interval timer for 40 rounds of 30-seconds work and 10-seconds rest; repeat the following sequence five times: 1. step-ups right, 2. step-ups left, 3. elevated knee tucks, 4. alternating leg lifts, 5. elevated lunge jumps right, 6. elevated lunge jumps left, 7. triceps kick dips, 8. hanging knee raises)
I just did this for the first time and man am I going to be sore in the morning. It says it's a leg workout, but it definitely works your arms and core as well.
