Heart monitor worthwhile for turbo trainer?

[Makhaira]

I've just posted another thread as I'm looking at getting a turbo trainer, which is new territory for me, and I'm unsure as to whether a heart rate monitor would be worthwhile so I can "gauge" how my workout is going. Or am I better just going off feel like I would on a proper ride?

Thanks in advance.

Honestly? No idea. I've never cycled indoors before so I thought I'd ask the question since I will mostly use it for quick blasts in an evening after work when the weather is rubbish, so I wasn't sure the best way to make use of my time/energy.
