Did the first day earlier this evening. Had hit up the gym in the early evening and focused mostly on back, and still had an empty stomach. But all things considered, had no issues. Granted it's only the first day tho. Took a before pic in the morning and I'll take one after the challenge is done for comparison. Still unsure if I'm gonna do it around the same time on the three days of the week like in the morning or at night. Or if I'm just gonna play it based on my schedule or mood. What I do think is i should have some water with me or stay hydrated, especially when I get to the higher numbers. Not looking to just work on my chest, but my overall core with this challenge. Would also help build some stamina. I usually like doing leg up pushups but I'll stick to regular versions for these. Maybe do leg ups on the next challenge.
