How do you utilize pre-workout for the most effective fat loss?
If you want to ensure that you see results using pre-workout, implement this process for safe and practical application of pre-workout supplementation:
Checklist:
Use in the right window: Consume pre-workout 20-30 minutes before you work out.
Hydrate: Most pre-workouts are diuretics, so be sure to drink adequate amounts of water to be well-hydrated.
Assess: If you are new to a stimulant, you can start off with half of a serving.
Don’t “double-up”: More isn’t better all of the time. Over-consumption of pre-workout supplements can lead to significant energy crashes and lethargy.
Cycle: Taking at least a week off every 6-8 to avoid desensitizing your nervous system and receptors.

High-Protein Diet: Protein helps with metabolism and provides satiety.
Daily Step Goal: Aim for 8,000-10,000 steps per day.
