Heavy Bag ~vs~ Heart Rate
One day a week the coach would meet with us to test and see if we were doing our roadwork. He would have us hit the heavy bag for 1 minute, then rest for 20-30 seconds, the he would check our heart rate. If our heart rate was high between 80-90% of the maximum heart rate zone and if it wasn’t going back down rapidly, this would tell him that we weren’t keeping up with our roadwork. Pretty interesting huh?
