It's in those last five seconds that I always want to quit. My muscles are exhausted. It's been a long day. I'd rather be reading a good book at home. It's hot. I'm thirsty. It goes on and on. And I used to quit. I stopped during the 5 second countdown. But not anymore. I was reading a career book by an incredible author and he randomly talked about how pushing through the last section of each interval (and consistently using heavier weights) is the most beneficial part of your workout. A time when you maximize your results and strengthen your mind.
I find it interesting how certain pieces of advice from the most unlikely sources can impact you. I've been doing this interval circuit training regiment for about 9 months now, and just recently I've started to see the biggest results. A trend which has only made me double down and see how far I can continually push myself.
As a quick sidetone, this super cool video about Sarah Gillette is quite inspirational. She's a great fitness trainer and has an incredible story. Enjoy!
