Exercise during TWW

[Conundrum12345]

Hi all

I'm very active and love exercising. I do crossfit 5 days a week and also run every other day.
Is it safe to keep this up during the TWW and first trimester (if I feel ok to, touch wood). My heart rate gets quite high during sessions

Thanks

I have been. The way I see it the fitter and healthier we are the better the chance of being successful with conception?
