I'm trying to train in zones, but when I use the rule of thumb provide by my HRM, I get a Max heart rate of something like 187 (220-33). Here is my real issue though: Whenever I train in zone 1, I feel like I'm getting no workout at all. In fact, it's sometimes hard to stay in zone 1, and when running (tri) it's practically impossible. Swimming, forget about it. Am I just out of shape?
For what it's worth I think (can't promise, but I'm pretty sure) that after on killer ride my heart rate broke 200 (205 maybe?) Is there anyway (without using a lab or spending $$$) to find out my real max heart rate so I can actually use zones effectively? Do I just ride until I fall over, then wake up and check my HRM?
The 220-age is a good starting place but don't put any money on it being accurate. The best indicator is the highest HR you see on the monitor after a lung busting sprint.
Zone 1 is basicly active recovery, so it should be very easy.
I've read its best to base your zones off your LT/HR , much easier to determine.
