I've worked with Mike for the past 5 years and he is an absolutely incredible trainer. I'm now stronger and in better shape in my mid-forties than I was in my twenties. We have worked on hip mobility following a surgery; through my training with Mike I am now able to do long distance running - something I never thought I could do. I appreciate that Mike starts off every session asking how my body is feeling so we can adjust as needed. The training sessions are never boring or repetitive and I always feel fantastic afterwards. I cannot say enough wonderful things about Mike!

Happy 5th to the best pawtner in crime Mobi. I wanted a dog that could keep up with my active lifestyle…I am still training to keep up with his. I wanted a dog that wouldn’t feel like a burden and could enjoy life’s adventures with me or just “boring” Costco runs. He is happy to do both. He has far exceeded my expectations of the dog I wanted. Help me wishing my handsome boy a happy birthday…sushi is on the menu today! #MansBestFriend

Froze my hand trying to film these…damn, I need a GoPro 😂 Mainly just wishing I was back on the slopes rn with all this fake snow we get here

Riding a high is easy. That’s what makes it a high. Results come from riding out the lows time and time again. This is called grit. Get used to it.

Even as a professional in the health and fitness industry, there are PLENTY of days I don’t want to “do it”. Life is hard and feels like it is pulling me in all directions at the same time. It’s fucking exhausting.

You have to stay disciplined during these times and stick to your routine. Start by stacking small wins.

Just get out of bed.
Just make your bed.
Brush your teeth and wash your face/take a shower.
Grab a quick bite to eat.
Grab your stuff and head out the door.

Going through the motions is tough. But we do it anyways because we know the result of not doing them. We’ve been there before and it wasn’t fun.

Ride out the hard times, find a friend/family member to help hold you accountable and keep going. It’ll be worth it, I promise.

Be more intentional

When it comes to power development, you won’t fool your nervous system with 50mins of trashy “HIIT.” You need to convince it. Every rep, every set.

On days where you’re focusing on power development, we typically need more time to recover between sets/reps or we won’t be able to repeat the exercise with the same high level of intent.

When we are truly doing 80-90% efforts each rep, we can’t expect to do a ton of volume either (like in a group exercise class). Days like these take significantly fewer reps because the high intent is extremely fatiguing on our nervous system.

Want to learn more about power development, shoot me a DM and let’s chat!
