Subject: ? about the "Phil Maffetone’s 180 Formula" I read an article about Phil Maffetone’s 180 Formula for heart rate training. It sounds great, but I cannot get it to work for me. My max heart rate would be 136 and min would be 126. If I start working at all, then I am way past these zones. Generally I am in the mid 140's and if I am cranking on the bike or run it might go into the 160's. Any BT's use this in their training program and how do you maintain your heart rate within the zone? Thanks, David |
