I am up here in Wales and have been using a local gym for my workouts. I love gyms, always have and always will. However, most people hate them. The great news is that you do not need to use a gym to get results. Since 2011 I have been working outside in parks, mostly Battersea Park and have helped many people get great results. There is a misconception that you need weights to do resistance training. The reality is you already have a weight, your body!
The video below was made for Rugby players and how to prepare for competition. It looks at how to use exercises for different training goals. Athletes use training phases, e.g. muscle building, strength phase, power training. This is to match the demands of the sport. While you may not be a rugby player you can take and use athletic training principles to apply to your fitness routine. It makes it more fun and effective.
