I train quite a bit, which frustrates the lady as I am apparently either at the gym, working on the car.....or on this forum
IMO the key to gaining the physique you desire is diet and rest, I believe both of these are more important that training itself. Without doubt 50-60% of it is nutrition. I am skeptical when it comes to ergogenic aids, especially pre-workout, both have had negative press recently and are extremely expensive due to the tax increase last year. I am a believer that you can gain everything you need from a strict, but balanced diet. Unfortunately steroids are rife in today's culture, and really are not the answer to gaining that 'beach body' image that the media portrays. I see so many 'newbies' that join the gym and immediately feel the need to turn to gear, usually because they are intimidated or have been ill-advised. Most women do not even like the big bulky look and it amazes me why blokes strive for this (it must be an ego thing or an association with perceived power).
Eat well, train hard and rest.
.....and the geezer above is on gear or has cycled lol
