Thanks for the input guys. Do you think these sorts of training programs are better suited a "beginner" more than a traditional 4 day split?
I'll give you guys some info. I'm 6 foot, 80kg with 18% BF. I eat a very well balanced diet with no processed foods and a good mix of protein, carbs etc. I keep it all recorded so I know it's on track too. I've increased by protein intake since starting the gym again.
When I was younger I trained from 17-19 heavily in the gym, mainly using circuit training due to playing a lot of rugby. I also did all the main compound lifts such as squats, deadlift, bench press etc. so I've got a reasonable idea what I'm doing. However I'm obviously out of shape slightly and will take a bit of time to get the form back for these main lifts.
I'd rather seek advice on here than on BB.com etc. There's a lot of great information on there but unfortunately almost every thread turns into a willy waving contest, making it hard to get the help you need.
