I'm still carrying on!
I now have a 5 pack! The top 4 squares and the bottom two are forming, at the moment just oneish but the right shape.
I've found going heavy helps. Do situps with a 20kg plate or the heaviest ball available, around 20 reps, about 5 sets. It hurts!
In terms of trimming and muscle, I'm not sure how you'd do both at the same time.
I'm about 5'6, when i was bulking up I hit 79kg, that was with shakes and good quality meat all day long.
Past few months I cut out all the shakes, and the diet in general is alot more "normal". I'm now weighing in at a far more trim 69-71kg.
I wanted to see how much strength/muscle i would lose.
Overall, no loss in strength, though recovery takes a VERY long time now.
Overall size, I'd say a little smaller, but alot more defined so in most cases people think i look bigger.
