I was so tired today, I almost convinced myself to stay in bed this morning! My body felt like it was exhausted from the workouts of the past few days, and I began to think that maybe I was just a LITTLE bit insane for getting out of bed and heading to the gym anyway for a HIIT. In fact, my quads are still spasming - they've been jumping around since yesterday morning's workout. So when I arrived at the gym, I gave myself permission to try out the treadmill, and then quit if anything felt too funny...I definately don't want to damage anything with a marathon on the horizon! I started with a nice slow jog for a mile (10:43), then hopped off and stretched for a minute. Everything was still working, so I jumped back on the treadmill and started the HIIT. I gave myself permission to stop for a walk between intervals, but as I got going, I thought that maybe I could do two in a row, then three, and before I knew it, I was finished! It was my first complete HIIT on the treadmill, without my cheater breaks! Now that it is over, and I survived, I'm quite certain I need to up the speed. I had started with a 6.0 MPH as my warm-up, then went from 6.5-9.0 MPH for my levels. I probably should shoot for 10.0 MPH, but I'm always afraid of doing too much and pulling or tearing something. That's why I've avaoided doing my HIITs on the treadmill to begin with! But 9.0 MPH was definately NOT a "10" for me, so I'll have to rethink that. I'm taking the rest of the day as a rest day, not because I wanted to, but because I have to go to a meeting tonight. I probably need a mini-vacation for my muscles anyway. :D |
