Training & Performance Booster

The aging athlete is concerned about maintaining lean muscle mass and sustaining energy levels. FIT40 Training and Performance Booster has a unique formula that can help replenish muscle energy stores that get depleted during high intensity training. When taken before or during exercise, the Performance and Training Booster can help you train harder and longer!

Ingredients like HMB, Creatine Monohydrate and Beta-alanine can help to provide support. However, it can be difficult to consume enough of these through food alone to help reach levels to support performance.

HMB supports muscle strength and rebuilding when taken over time with regular resistance training. HMB also supports recovery after intense exercise.

HMB is a metabolite of the essential amino acid, Leucine.

Creatine may help to support performance and ATP recycling when taken over time with exercise. Every cell in the human body needs ATP to function. Muscles also rapidly use ATP when contracting.

When taken over time, beta-alanine may help to support muscle endurance. Beta-alanine supports carnosine synthesis, which helps buffer acid in muscles. In turn, potentially delaying muscle fatigue.
