man most of those are really good exercises but you are doing half of them pretty wrong, i'd advice going slower on the reverse nordic for your level, and put your all leg on the platform for poliquin step ups damn you should push from all your feet your'e missing on much more power and finger muscles in the feet, also for the tibs you should lay on a wall to create an angle, and there are many more mistakes, anyways good luck man
Great video. He did the stretching in the middle because of the leg exercises you did after. They are pretty intense. Also for the tibula exercises. Use a kettle bell if you can find one. Keep it up. More content!
