**TL;DR:** Did a month each of high carb and high fat pre-workout meals. Carbs gave me more energy and better lifts, while fats felt stable but sluggish.

So, I've been experimenting with high carb and high fat pre-workout meals for about a month each, trying to see which one gives me the biggest pump for my lifts. For the carb phase, I went with oatmeal and some fruit, while for fats, I tried avocado and nuts. 

**Here's what I found:**  
**High Carb:** Felt like I was running on rocket fuel! Energy was through the roof, especially for my leg day. PR'd on squats with a solid 3x10! My muscles were like "let's go!"  
**High Fat:** More of a slow burn, I guess? It was chill, but I didn't feel that immediate spike. Lifts were decent, but not as explosive as the carb days. I felt more steady, but kinda sluggish at times, especially on heavy deadlifts. 

So, if you're looking for that quick energy boost, carbs are king! But if you prefer a more stable energy without those crazy spikes, fats might be your jam. Ngl, I'm leaning towards carbs for now, but anyone else done this? What were your vibes? 🤔

  I tracked my heart rate during both carb and fat pre-workouts, and I noticed a significant difference in performance metrics. Carbs increased my intensity and focus for HIIT sessions. Fat didn't do as much for my HR.

    Dad tip: I prep oatmeal pancakes for my kids and sneak some in before my workouts. It's like a double win, healthy for them and me!

    Oatmeal gang! 🍚 Nothing gets you more pumped than a bowl of oatmeal with some honey and fruit. It's like a pre-lift pizza party.

      While I don't lift heavy, I still feel that carbs help me with endurance in calisthenics. I can do more reps without crashing. Anyone else noticed that?

      Carbs give me life, especially on longer runs! For lifting, I feel like they help sustain energy much better than fat. It's all about what works for you, I guess.

  I love that you're experimenting! For my high-carb meals, I make a mix of oats, banana, and a little almond butter. It gives me a nice pump, plus it's super tasty! For fats, I usually stick to nut butter and yogurt, but I get what you mean about that slow burn

    100! I love that you're all about experimenting too! Everyone's body reacts differently, and it's cool to see what works best for you.

  I've been sticking with carbs too. Oatmeal and a protein shake about 30-60 minutes before lifting has worked wonders for me. Solid energy without crashing.

  this! Carbs hit different when you're about to crush leg day. It's like your body is saying 'let's do this!'

    Facts! I tried high-fat pre-workouts once and felt like I was in slow-mo during my sets. Carbs are way better for those explosive lifts.

      As a marathon runner, I find carbs essential not just for lifting but for endurance too! It's interesting how different types of training demand different fuel sources. My pre-run snacks are always carb-loaded, and I can feel the difference.

      Honestly, I thought I was just being lazy when I tried high-fat meals and didn't feel the same energy. I was so sluggish during my workouts! Guess carbs really do reign supreme for lifting.

        I'm still figuring out my pre-workout meals, but so far, carbs seem to work better for me. Fat just makes me wanna nap!

        My buddy tried a high-fat pre-workout once and ended up regretting it on leg day. He barely made it through his sets. I've been there too, it's hard to lift heavy when you're feeling sluggish. Carbs are the real MVP!

        You can also play around with timing! Eating carbs about an hour before your workout seems to work better than right before. That way, you can avoid feeling sluggish. Just a thought.

  I always say carbs before heavy lifting. They're the real deal if you want to hit PRs. I loaded up on rice and chicken before my last deadlift session, and my 1RM shot up!

  You know what's funny? I used to think high-fat was the way to go until I hit a wall during my squat PR attempts. Nothing beats a solid carb load before going heavy.

  I'm all about that simple approach. Just make sure you track your meals. I keep it to the basics, and it's been working. My gains have been solid!

  Bro, carbs are life! I load up before workouts, and it's like flipping a switch. Always feel strong and ready to crush those sets. Fat meals just don't do it for me.
