For abs don't forget to squeeze for 2 seconds at the top. Abs are slow twitch muscles and stabilize all day so they do well with high reps. Once you build up your endurance, add weight but don't use it for movements that target the obliques if you want to keep your waist small. Abs are ideally done as supersets and giant sets.
If you ever feel hungry load up on sulfur rich veggies that help detox like broccoli, cauliflower, cabbage, and brussel sprouts. The fiber helps you stay full!
