I'd be substituting the fruit salad for 2 bananas, they have less simple sugars than fruit and more protein and calcium well as potassium, lectin and Vitamin B6. Also have a protein shake 2 to 3 hours before training. Listen to some raw, energy pumping music on the way to the gym and at the gym (I like RATM, System of a down, Korn, Eminem, Bring me the Horizon)
When I'm at the gym I have a specific goal that I need to achieve such as an extra 2.5kg on my last 1RM or more reps on a set; this helps stay focused and gives my session purpose, which assists in feeling energetic.
What you do after training is just as important for the next session, magnesium, protein shake, protein / carb rich meal, sleep
