‘Long’ 16-24 Week Preps
The ‘standard’ prep time for most bodybuilders used to be 12 weeks, but as the years have gone by and conditioning has (on average) gotten sharper year on year, prep times now seem to average around the 16 week mark, with lots of natural competitors actually going up into the 20+ weeks.
These are the two main reasons to opt for 16+ week preps. A longer time period allows for more fat to be burnt, coupled with the fact that you have a better chance of protecting the muscle mass you’ve worked hard for in your Investment Phase.
‘Short’ <8 Week Preps
Short-term dieting is not without its downfalls however.
