Hi, I prepared my body in a way with intermittent fasting. Started with the 18/6 window where you eat for 6 and fast for 18. Then went to Omad and alternate day fasting. I just decided on the date and went for it. I journal everything, been walking a minimum of 3kms Mon-Fri and on a weekend I push 8kms(always in a fasted state). Whilst on the water fast I walked 3 days out of the 5 but it drains me. Should you embark on this, please make sure to do your research and have electrolytes (sodium, magnesium & potassium) otherwise you'll be in so much pain. Perhaps try a 24 hour to start and see how you feel when working out in a fasted state. Hope this helps, all the best!
