2 TNT-type questions

[Sinker]

1a) I started riding a mountain about a year ago and really enjoy it. Unfortunately, the timing of good riding weather the past few weeks coincides with my starting TNT, and my legs are TIRED. I try to ride two or three times a week, and while I'm pretty slow I still tax my legs pretty well. Add to that the TNT workouts lunges, goblet squats and step-ups and my legs really feel fatigued. Problem is, I don't want to give up either activity. I generally lift in the morning and ride later on. Is it best to do those both on the same day so I have a rest day or to ride on days I don't lift?
1b) Does a lack of carbs contribute to this fatigue (will it pass)?

2) The TNT exercise 'Seated Rows to Neck' is an extremely awkward movement for me; especially as I approach my neck. I'm pretty sure I'm doing them correctly, but I really have a tough time with those last few inches as I get towards full contraction, even with an embarassingly light weight. It's a little easier if I drop my elbows, but that's not how it's shown in the book. Any suggestions?

2. You might consider substituting face pulls for the seated rows to the neck. They work the same areas, serve the same purpose, but are much more comfortable to execute.

There's video of Bill Hartman doing a face pull in this article: Push-ups, Face Pulls, and Shrugs

Thanks, Lisa. Better than a fix - an upgrade!
