Pros - The heavy training CAN help you retain as much size as possible while you are restricting calories in a typical "cutting fashion". Many people equate cutting with doing high reps which only makes them look stringy and flat.
Cons - Dropping the calories down while continue to train heavy can tap into the CNS more aggressively and may lead to overtraining where all gains come to a halt. And there can be a risk of injury by working a muscle heavy over and over while only feeding it a minimum amount of nutrients to repair itself.
If you want to incorporate 5x5 training with leaning up, I would suggest it to be like this :
Divide your prep time into two parts. The first half you will continue to eat the same amount of food. But CLEAN food. Nothing out of a bag or box. Complex carbs only before 2PM and carbs from leafy greens afterwards. No carbs of any kind past 8PM. (Assuming your life follows the usual 9-5 routine). During this time your fat loss will come a little from the training itself, but also from INTENSE 15 minutes cardio afterwards. I don't mean riding the bike. Wind sprints. Pounding the boxing bag in the gym. 15 minutes nonstop basketball hoop shooting with 5 suicides after each miss.
Second half of your prep you will still follow the 5x5 system, but here you will DECREASE the cardio. Still 15 minutes post training, but this time on the treadmill at a brisk walk. You will lower the calories by eliminating carbs first at this time. You will have prepped your body in the first half here to get ready to shed the fat, now you will be actually shedding it via diet as opposed to burning it through cardio.
GR8 response AAP and much thanks bro.
Ok when you say cutting cals to a minimum, that is not exactly my plan. I was thinking maintinance level for a given body wieght, is that what you are talking about, as opposed to a deficit cal diet?
In the fist half you are talking about Tabata type of cardio? I know that system says 10 mins and you say 15 mins, but still meaning all out effort is this correct?
Any commnets on the "supps" I was considering, or maybe something diff alltogether diff?
