I’ve decided to switch things up a bit the past few days and try some HIIT workouts on the treadmill. Yesterday, I did a routine of jogging comfortably for 1 minute, then running for 1 minute, and finally not-quite-sprinting for another minute for a total workout time of 21 minutes. I definitely didn’t push myself as hard as I could have, so today I kicked it up a notch: intervals of 2 minutes running and 1 minute sprinting for a total time of 21 minutes.
I’m not convinced, however, that the speeds on my treadmill are all that accurate. I have a Weslo Cadence 200 cs (it was a birthday present *years* ago, and according to product descriptions online, I’m surprised it has lasted me this long). According to product descriptions online (since I have no idea where the owner’s manual is), the speeds are literal: a speed of 3.5 on the dial is equal to 3.5 mph. However, I was using a 5.0 to “sprint” today, and I certainly don’t remember running THAT hard when I was half-marathon training and getting 5 miles in under an hour. Perhaps my perceived effort feels exaggerated on a treadmill? Regardless, it was quite the workout and I kept my heart rate higher than yesterday’s workout. My average heart rate for the entire workout was 87-88% of my maximum heart rate, while the highest rate I reached was 95%. Oh…and my legs felt like jello by the last 2-3 intervals.
I’m considering switching gears and focusing more on strength training every other day and adding in a HIIT treadmill workout on the days in between. I’m also anxious for the weather to finally pick up so that I can try these workouts on the track. Cross your fingers that the extended weather forecast is accurate so that I can possibly start next week!
