The best type of workout split is a 2 or 3 day training split. Again, progressive overload is behind the increase in the number of sets per bodypart for advanced trainers. As muscles adapt, increase the amount of stress they receive. One way to do this is to increase the number of sets performed. Of course, the increase only enhances strength to a degree.
Just after the album The Beatles came out in late 1968, Lennon performed Yer Blues at The Rolling Stones Rock and Roll Circus with a supergroup dubbed The Dirty Mac, consisting of himself, Eric Clapton on lead guitar, Keith Richards on bass, and Mitch Mitchell of the Jimi Hendrix Experience on drums.
Brian used a Harmony Stratotone in the early days of the Stones playing the Blues clubs, but he soon replaced that with a Gretsch Double anniversary in two tone green. He used this up until 1965 when he started to use the guitar that he is most known for, a Vox Prototype Mark IV or Teardrop guitar.
