Getting to the gym can be hard when you’re tired or just plain lazy. Pre-workout supplements are your motivation in a bottle.

They’re loaded with stimulants and boost your endurance. They’ll also plump your muscles and dilate your blood vessels.

Five years ago, I had my first experience with a pre-workout called “N.O.-XPLODE”. Since then I’ve rarely made it to the gym without a pre-workout. These products are effective and the results are addictive.

A main ingredient in many of these supplements is caffeine. How much caffeine?

A single serving of ADVANCED STRENGTH N.O.-XPLODE 2.0 has approximately 225mg of caffeine according to the label. For comparison, a serving of Red Bull Energy Drink has 80mg of caffeine. However, I’ve gradually increased my pre-workout dosage of N.O.-XPLODE to 2 servings! Again, for comparison, the caffeine content in 2 scoops is equivalent to 5-6 cans of Red Bull!

Too much caffeine can lead to heart issues, difficulty sleeping and risk of stroke. The safety of pre-workout supplements is still relatively unknown, so proceed with caution and consult your doctor.
