Rugby players aren't just big and strong.
They're also athletic, fast, and powerful... not to mention superbly conditioned so they can run and hits rucks for the full 80 minutes.
Professional rugby players ALL use a special training strategy to pack on lean, athletic muscle as quickly as possible while developing speed, strength, and power.
It's called PERIODIZATION.
It means dividing your training into periods or phases that target a specific part of performance. By fitting phases together in the correct order you will experience rapid muscle and performance gains.
