Caffeine Before Workout: Friend or Foe?
Tuesdays are pretty rough for me. Not only are they big work days, but I have an afternoon full of errands to run. By the time I can get to my 7 - 9 P.M. weightlifting/HIIT/martial arts training session, I'm totally exhausted and ready for a nap! Last week, I tried something new: I had a coffee around 6 PM. When I went to work out, I had tons of energy, and I actually made it through the 2-hour workout feeling great. That got me thinking: Is it bad to have coffee before a workout?
Downsides to CoffeeWe all know that coffee does have its downsides:
- It raises your blood pressure
- It affects your nervous system
- It can cause acid reflux and digestion issues
- It reduces blood flow
Pre-Workout Cuppa JoeAccording to a Men's Fitness article, drinking some coffee can help to boost not just energy, but endurance as well. Seeing as HIIT is all about that endurance and stamina, some coffee may not be a bad thing!
