I hit HIIT yesterday (didn't have time to post), and it worked pretty well, I did it on a traditional bike and I could feel it more. Leaving, it wasn't as bad as that day, I actually flirted with the girl at the counter and told a few jokes to one of the trainers, but I could actually feel it this time, it took a toll.
Very nice. Did you see if they had light weight olympic plates? If so, and there is a clock you can view with a second hand, try clean and jerks for your tabata starting with 65 lbs (the bar and 2 10s). The reason olympic plates work better is because of the bar height. Whether you are working with 10s 25s 35s 45s etc the bar will be the same distance from the ground. If you don't have them, then load up normal 10s and start from the hang position instead of the floor.
Then do the bike tabata, then do the one minute high one minute medium intervals.
You are young and your body seems pretty resilient. We'll need to push it to see how far we can go without overtraining. An old fuck like me wouldn't attempt to do these tabatas alongside the weight training program you have but i think you can handle it.
