Concentration is key when it comes to completing intense training, hitting a new PB or maintaining a mind muscle connection. Improved concentration and mental focus in the gym results in better quality training sessions, which in turn results in better results. Supplements which aid concentration and mental focus come in various forms. Ingredients which promote this are often included in Pre-Workouts, Fat Burners or Nootropics. These supplements are also commonly used to support concentration at work or on a day to day basis.
