1. What kind of trainer are you using?

2. I'm not sure how to remedy this.

3. Is the HR built in to the watch?

Heart rate is in the watch.

Ok, perhaps your FTP is a little lower than you thought? You can do a test in zwift, but do a few rides at 90% then see how you are going, and perhaps either leave as 90% for the plan, or gradually increase to 100% as you get used to the way that the sessions stretch you. Either way, you're doing work and getting stronger, for the first few weeks then don't sweat the details, just get used to riding and the routine. One thing to ask, was your FTP figure from the Flux or from some other source? I ask as there's about a 10-15watt difference between my Neos (2x) and Quarqs (3x) which I put down to drivetrain losses. Now at 300w that's not a lot of difference, but when doing low intensity stuff then it does become more noticable).

Unless your watch broadcasts (don't think it does) then you won't be able to use that. In all honesty then I've not found my FR935 all that good on the on odd occasion I've forgotten my chest strap, and so if you're going to be zwifting a fair bit then I'd suggest getting a chest strap for using.

I'm on a PC with ANT dongle, so can't help you with apple stuff, but memory tells me that apple is bluetooth only and not ANT so be careful which strap you buy.

Thanks and maybe it is the variation in testing. My FTP seas not from Zwift with this trainer. So I will dial it back until I retest.

Yes, you do need to retest your FTP in Zwift using your current trainer. Just do it.

Yep, do the Zwift FTP test and you should solve your issues, or move your powermeter from your outdoor bike to your trainer bike. Most of the basic Zwift plans are actually pretty easy the first week, then they get harder.
