I just failed my first recommended workout since November.

Got three quarters of the way through #3 and bailed. Then muddled through #4 and #5 at 90%. Coulda gone higher but once you talk yourself out of one it’s hard to get back on track. 
My point is you can go a long time completing workouts at 100% difficulty with Xert.
That hasn’t been the case with other platforms I’ve tried especially TR which I expected to be better than canned plans I followed in the past. It wasn’t but I shouldn’t have gone down the SS rabbit hole (twice) before realizing that approach wasn’t for me. Xert has been a revelation in that regard.
Which would you rather do? Follow a plan that ends in DNF and failed workouts or learn a method of training that produces better results and doesn’t drive you into a wall?
I’ll post more about my Covid-19 stuck indoors experiment at some point.
Title will be along the lines of “100% at 100% for 120+ days”. Pre-Base to TED.
