I'm going to start with some Tabata cycles but I'll also throw in more kettlebell complexes, walking, swimming, biking, cross country skiing, etc. and cleaning up my diet to hit this goal.
Today I did a standard cycle (20 seconds work, 10 seconds active rest for 8 cycles/4 minutes) with jumping jacks. Next time I want to measure my heart rate immediately after and then at either 1 or 2 minute intervals until I've come down to a normal or near normal heart rate.
Hopefully I'll also get in another pinch workout this afternoon and I may walk on the treadmill for 30 minutes or so.
