HI!
1. I cut down all my exercises to at least 4 sets instead of the 5(except for chest exercises and biceps) --this proved to be effective as it meant i weren't over-training the body and spending too much time in the gym.
2. The arms training I'm finding difficult because Im not sure which 3 exercises is best, I tend to respond to isolation exercises best, like one handed curls or preacher curls but I am not sure if this is the best plan to follow since I want my arms to grow rather than just be small and defined.
3. I changed my diet since it makes a huge difference, I really only find time to eat 4 times a day, this is pretty good in which I load myself with quality carbs and protein in the morning (after training) and afternoon, then I will have just a pure protein meal like fish or a mrp, then for dinner Ill a protein and salad meal. Depending on how intense my training was, I will eat a few more times.
4. My calves are not responding to once a week training so I do a 2 day split routine for that, but would it be best to do donkey raises, standing raises and seated raises on seperate days twice a week or altogether twice a week?
5.Am I doing enough chest exercises to pecs exercices? My chest is huge and is heading to outproportion my pecs.

I find myself with a lot of energy now following this programme compared to my 6 day a week programme, is that a good sign? because sometimes I wonder if I should take to the gym again on the same day to work at something else

Many thanks
