I have had good success while fasting and training last year. I can eat between 730 pm and 6 am so slightly longer window than you.
I would recommend working out at night when you can actually eat. workouts are hard enough as it is, minus food and water would put you in a world of hurt (like even more hurt than TR hurt).
I was in the specialty phase last year and I would workout around 10 pm (roughly 2 and half hours after breaking fast). I would also have a pre-workout meal before the workout usually a bowl of oats and have another meal after. I know, 11 pm meals sounds pretty bad but you will need the calories if not you’ll be dropping some serious weight. I lost 3 kg during that month alone (weighing 63 kg at 167 cm).
I will be doing the build phase low volume right when fasting month is coming up so I will do the following:
- Break fast at 730 pm
- Eat 15 mins before workout
- Workout at 10 pm
- Second Meal after workout
- from 730 till 10 I’m pretty much constantly munching on food
I may or may not get up to have something to eat at 5 am but usually I don’t.
You will need to experiment. If you do wish to try working out during the day, keep it 45 minutes or less. Start with 30 mins easy workouts and see how it goes. I never tried a full blown 1 hour TR workout during the day, only short ones.
you could also shift your focus to maintenance rather than building fitness if its your first time through fasting month and training. For me, its a great time to build fitness as my food intake is exactly the same time and roughly the same amount every day for 30 days.
hope it helps.
