Peter is a fantastic trainer. He tailors his program to your individual strengths and weaknesses and always stresses the importance of correct technique.
In less than 6 months with Peter I have seen significant gains in my strength and physique.
On top of this he stresses the importance of eating the right foods - I definitely have a much better understanding of the different qualities of foods that I consume.
I'd recommend him to anyone looking either to gain muscle mass (like me) or lose weight.
