Aim higher, dream bigger.

But what if I fall?
But what if you fly?

If there’s one skill I have as a Personal Trainer, it’s the ability to make people do things they don’t want to do because they don’t think they can do it.

And often, all it takes is for one person to say, “I believe in you. Go get it”.

So it was, 10 clients, some reluctantly agreeing, others kicking and screaming, to put themselves in the arena and face up to vulnerability outside of their comfort zone.

Our first .fit games and the squad came good.

For some, things got dark and they had to dig deep.
My voice in their head: “This is just another training session like all the ones you’ve done, with a shiny medal at the end”

The highlights were observing all the team delivering textbook movement standards without cutting corners. A son watching her mum lead by example, conquering those burpees despite suffering cramps. A wife watching her wife grow from strength to strength ticking off yet another challenge this year of challenges. Guys doing the hard thing in preparation for a bigger challenge yet to come.

And somewhere amongst the midst of me being everyone’s biggest cheerleader, I had gone and podiumed by finishing 3rd myself.

What if I fail in front of all my clients?
What if you fly and bloody podium third?

The point here: if your goals don’t scare you, you’re not dreaming big enough.

This one is for the guys!

Our next deadlift party will be to raise vital funds for a men’s Mental Health charity.

12.5% of men in England experience mental health issues. Pressures to remain stoic or “tough” cause many men to hide their distress. Sadly men are 3 times more likely to die by su***de in England than women. We want to do our little bit to help.

Our deadlift party format is simple, we lift one max rep and take in turns until we bow out at a weight we feel hits our current max. There will be alcohol-free beer, good music and a great supportive vibe where we can cheer each other on and get stronger together. You don’t have to know how to deadlift as we will do a mini workshop to ensure good form and that no one gets injured.

It’s £30 for two hours on Sept 22nd 7pm. We are opening this up to any guys that want to come. You don’t have to be an Underdog client.

Let’s lift some heavy s**t chaps! Who is coming? DM to secure your spot 💪🏽

We’ve had quite a few new followers on our socials. So here’s a hello and a warm welcome to Underdog 👋🏽

We might be s**t at content creation, but we’re great at helping people discover the joys of moving their bodies. From newbies becoming stronger, to helping runners becoming faster. We help people build confidence so that they unapologetically take up space in conventional gyms.

At underdog, empathy is our big thing. I was once disabled, and so, I have an affinity of what it’s like to start from rock bottom. As a Personal Trainer who came to fitness with a broken body following multiple spinal surgeries, my priority is to ensure we prevent injury during training. The focus is on good form and earning the right to go heavier.

We offer one-to-one personalised coaching as well as small group shared PT. We also have our inclusive functional fitness classes and our popular 90 minute weekend Hybrid sessions that combine power with engine.

Our own little fun run club truly is for all paces because our ethos is everyone starts somewhere and walking pace is sexy pace. Conversely, as a Hyrox affiliated performance coach, we have fielded over a dozen athletes to Hyrox races, who’ve gone on to achieve personal bests.

If your goal is weight-loss, our inhouse NHS clinical
Dietitian can help. We are a GLP-1 welcoming space with experience of training clients that have ongoing side effects from the medication. We also specialise in cancer rehab PT so that you can rebuild your life, celebrate your next exciting chapter and becoming more resilient than ever.

Our setting is like no other. Facing the Walthamstow wetlands under the big sky, we train in a courtyard garden surrounded by nature and wildlife. Our goal was to be as far away from the triggers of unwelcoming gyms. Here you won’t find loud obnoxious music, the mirror-obsessed or egotistical-lifters.

Our little community cheerleads each other because when one of us wins, we all win 🏆

From metal screws to metal medals.

I’m 50 this year and proof it’s never too late to reclaim your health.

When your broken body makes the mountain to climb ahead impossible, know that all we have to be is just 1% better today than yesterday.

The gift we have is knowing what real pain is. This becomes a super power no one else has.
