Here’s one way.
We had a guy come in one day and take a look around. He said it looked like a good place to work out but he wanted to know where the treadmills were and I told him we didn’t have any. He got flustered and said,”But how do you do cardio?” Some people just don’t get it. So here’s one way we do cardio: push the weight sled.
I originally planned to keep my heart rate at around 130-140 by dropping the weight but my ego got the better of me and I kept it pretty high the whole time: around 150-165. I only rested just long enough for my heart rate to drop back to around 145 or so and since I was wearing the heart rate monitor the whole time, it was easy to track so I didn’t cheat. When I used the carotid pulse and look at my watch method in the past, I sometimes over-rested and made the workout easier. Not this time. Enjoy.
Oh, and if your gym doesn’t have a weight sled, join a gym that does — like Formosa Fitness. 🙂
