Thoughts on Target Heart Rate?

[Catrin]

I've heard of exercise induced insomnia but always thought that it was caused by working out too late in the day. I finished my ride by 1:00. I never would have considered that the additional exercise that early in the day could affect my sleep.

I swear that I learn something new every day on TE

Personally, I've found that if my exercise is above a certain intensity level or longer than a certain number of hours I always have at least a touch of insomnia - regardless of how tired/sleepy I might be before bed. I've not heard it described that way, but that is how it appears to affect me. I've always heard it the way you describe.This is one reason I don't like to have my long ride on Sunday as it increases the chance I will go to the office tired the next day. I also can't have even one beer too close to bedtime - or I've the same problem. It may be that I am just prone to that type of insomnia which makes it more likely for non-traditional triggers.
