No matter your goal, we've got a stack to suit you! Wanting to shred some extra fat? Keep reading.

The F45 Challenge Fat Loss Stack contains:

To optimise your fat loss results, we recommend the following:

  • 1 scoop of Oxyshred either 15 minutes before training or first thing in the morning on an empty stomach if you are training in the afternoon/evening
  • 1-2 scoops of glutamine before training (can be stacked with Oxyshred)
  • 1 scoop of protein post-training

Why these products?

Oxyshred is a potent thermogenic fat burner. It works by inducing hyper-lipolysis which is a complex process of super-efficient and ehanced burning of the subcutaneous fat molecules. This means it will maximise your results when paired with proper nutrition and exercise. Plus, when taken before training, it will give you a boost of energy to push yourself even harder. 

Glutamine is the most abundant amino acid in your body, but it reduces with stress (emotional and physical). It preserves the architecture of the muscle tissue and prevents the skeletal musccle being broken down for energy. With high intensity training like F45, supplementing glutamine is recommended. Taking 3-5g per day has been shown to support immunity, enhance recovery, boost lean muscle gain, and support healthy gut function.

Protein is the most important nutrient for weight loss. A lot of people struggle to consume a sufficient amount of protein each day, so a shake is a useful tool to boost this. A high protein diet helps to build lean muscle when combined with exercise. This then works to boost your metabolism and burn more calories, leading to weight loss. It can also help to reduce your appetite.
