Supersets or Compound sets?

Most of us have heard of supersets and have most likely used them in our training at some point or another, either to save time or to make us feel like we are working harder. Strangely though, you may actually be performing compound sets and not supersets. Super vs compound…

Do You Need To Be More Social Media Selfish?

Last week I saw the very knowledgeable Andy McKenzie put something on his Instagram about being selfish to be happy. I’m not going to go into the ins and outs of that post, other than to say in general I agree. The bits and pieces I have utilised from NLP and my own personal…

DeadPool Movie Review

Deadpool I was asked to write this review as I’ve been a Deadpool fan for sometime. I have been waiting for this movie since Ryan Reynold’s (half) took on the role for Wolverine Origins in 2009 and since 2010 an IMDB page has been up declaring the movie in pre-production….

Time For A Change?

How to start a fitter lifestyle is something I get asked about a lot. Whatever I seem to be doing work wise from day-to-day, or when I meet people socially; once they find out what I do/have done and that I have some knowledge in the health and fitness field,…
