Lest I forget...
1 minute being an intense whirlwind followed by 5 minutes being a breeze, 1 minute rest. Back to 1 minute whirlwind, 5 minutes breeze. Repeat this cycle 4-5 times. After a couple of weeks, try to do it in the same way 1 minute whirlwind but this time only 3 minutes breeze. That way the intense sessions come more quickly. When you can do it 4-5 times in a cycle only resting that 1 minute in between cycles, then increase it up some, but in the same format. This time it would be 2 minutes whirlwind 5 minutes breeze 1 minute rest. Few weeks of this, adjust it like before. 2 minutes whirlwind, 3 minutes breeze, 1 minute rest
