Endorphin Mood Swings.

TGIF! Here in Canada this weekend is Thanksgiving weekend so we get Monday off! I have the weekend off of work and I have tried to stay as caught up as possible in my school work so I am ready to relax for a few days. I was so over it being Thursday yesterday – in case you didn’t get that from my Instagram 😉

Yesterday I didn’t work out in the morning. Don’t all gasp at once. I got to bed at about 10:53 pm on Wednesday night and setting my alarm for 4:45 am to get in a workout before school was just not happening. I knew that I wanted to go to drop-in spin with my mom in the evening so I gladly slept in until 6. It just always feels weird to shower when I am not disgustingly sweaty. After school I ate dinner # 1 at about 4 pm because digesting before this intense spin class is essential. I want to vomit during class when I don’t have food in my stomach, I couldn’t imagine what would happen if I ate just before class. I was in a bad mood. I wasn’t hangry because I had just eaten (<– most common reason for me to be in a bad mood, 99% of the time my hunger just takes over my emotions) and I wasn’t tired, so there was really no explanation for my attitude. 

My mom and I went to the gym early to get in some ab work (her) and a couple of miles on the treadmill (me). I ran 3.0 miles at an 8:28 min/mile pace. I knew I had to save my legs for what was coming next. Even after that 25 minutes on the treadmill, there was a noticeable shift in my attitude. I was no longer as much of a smart ass and I wasn’t being as rude to my mom. Endorphins at work.

We headed up to the drop-in spin class that we have been attending for the past three weeks. We dread it, we mentally prepare ourselves for it, we are sore for days after this class, but it is SO GOOD. One of the hardest spin classes I have ever done, and that includes the Advanced Spin class I took in the spring. 

We sweat so hard and my mom claims she almost vomited three times last night, but it is so worth it. I hit ALL of the target gears and speeds last night and I was so proud of myself. This instructor is amazing but VERY difficult. She gives specific ranges of gears which is good, but those ranges are really high and really hard, so it is a struggle to even get to the bottom of her chosen range. 

60 minutes of spin = a whole new Kris. Apparently I am susceptible to endorphin-enduced mood swings.

When we got home, we arrived to see the this: the most common evening sight in the Murray household for the next 8 months. Neither of them read my hockey workout post so they weren’t even doing pushups or anything while watching the Habs game. Rude. 

I had dinner # 2 of a chocolate and peanut butter protein shake (Chocolate whey protein powder, no sugar added soy milk, PB2, and ice) and some dates because those things are addicting and practically pure sugar. The healthy sugar though 😉

I was in a good mood for the rest of the night. The end.

I couldn’t believe how much endorphins changed my mood yesterday. I am not a really mood swing-y person (don’t verify this with my family, just trust me) so I had no idea why I was being such a downer, but then when I started my run, it hit me that I hadn’t had any endorphins in my system yet that day! Lesson learned: always workout in the morning or warn people that you haven’t had your daily dose of endorphins yet.

Have you ever experienced endorphin mood swings?

What is the hardest workout (not running) that you have ever done? Spin classes get me every time!


  1. Body pump was a tough workout for me the first time! Super sore glutes!!! I definitely have endorphin mood swings. I notice it especially after a marathon. REALLY up and then DOWN. :S So weird.

  2. I work out in the morning to get that endorphin high too. Apparently I’m not very pleasant if I don’t workout (who knew??) I can’t imagine how unpleasant I was before I started running last year lol!!

  3. I’ve had plenty of days where I’ve felt in a funk and then had it fixed by endorphins 🙂 They work magic. Spin class is definitely hard! For Thanksgiving (in the US) 2012, my gym had 4 spin classes back to back and then they closed early, so my mom and I got up and did 2 of them. The first hour was super intense heavy gear work, then the second hour the instructor did mostly standing sprints, and I thought I was going to die haha. I actually watched hockey for the first time last night while running! I might have to watch it more, it was entertaining 🙂
