Depending how far out you are from it, start doing weighted stair climbs with up to 75lbs. The stair climb is the first station because it’s the hardest and will turn your legs to mush. The rest of the stations are a breeze. So just get yourself ready for stairs. 10min 20 seconds is plenty time to get it done.
If you have anymore questions about any of it, shoot me an ask. Hope this helps!
