Rain, Deer & Deliver: GoodGym Barnet Spreads the Cheer

Barnet Report written by Paul Salman

We gathered at the Phoenix Cinema, full of festive spirit and only slightly intimidated by the kind of rain that looks like it’s been booked specially to test our resolve.

But, as every seasoned GoodGymer knows, the weather is never the boss of us. Sure enough, by the time we set off, the rain eased just enough for us to get moving in good spirits towards Grange Big Local estate in East Finchley.

We were meeting Emma and her brilliant volunteers from Hope North London, who are working hard to support families on the estate with Christmas lunches and festive essentials. Our job: deliver their Christmas packages to every home across the estate.

Once paired up, we were off. I teamed up with Rachael, and between us we somehow managed to do three blocks — popping back to reload like festive posties on a mission. Other teams powered through their routes too, and in no time the whole estate had received their Christmas deliveries.

With the job done and the warmth of good deeds carrying us home, we jogged back to the Phoenix for our stretch-down,

Then it was straight on to the White Lion for our Christmas get-together — good food, good chat, lots of laughter, and plenty of cheer to round off a brilliant year. let’s shout out for Narina on her first outing what a great one to be involved with!

⭐ Milestone Shout-Outs

A big festive cheer to: • Daniel M. – approaching 100 good deeds • George T. – also closing in fast on the 100 mark and for sorting out the Christmas meal! • Narina](/v3/profile/narina-bira) first ever GoodGym session (welcome!)

A fantastic outing and a reminder of what GoodGym Barnet does best: turning up, supporting our community, and having a brilliant time doing it.

Yogata visit Stephens House and Gardens

Barnet Report written by Paul Salman

A special yoga morning at Stephens House & Gardens

Instead of our usual online Tuesday session, Stephens House kindly offered us a beautiful room to host a live class — and what a treat it was. A huge thank-you to Malcolm the manager for making the space available.

We had a lovely mix of GoodGym members and local supporters of the House & Gardens, whether through volunteering or donations. It was great to see everyone gather in the Stephens Room — once Sir Samuel Stephens’s own laboratory — with those stunning views across the gardens.

For anyone who couldn’t make it in person, I broadcast the class online as usual, so I hope you still felt part of it.

Thank you to everyone for coming along and supporting the House. Let’s hope we can do it again in the new year.

Have a wonderful Christmas — keep moving, stay well, and here’s the yoga thought for the day:

Yoga Talk : Encouraging Healing Through Gentle Movement

Yoga uses controlled, low-impact movement to gently “wake up” muscles and tendons. This stimulates healthy blood flow, supports tissue repair, and helps reduce stiffness. By balancing effort with rest, yoga becomes one of the most effective ways to maintain mobility and recover from everyday aches or longer-term injuries.

Tiny Forest, Big Science!

Barnet Report written by Daniel Mermelstein (He/him)

Four goodgymers joined the local community for a day of activities organised by environmental charity Earthwatch at the Mutton Brook Tiny Forest. Adults and children enjoyed a full day of citizen science: measuring trees to calculate carbon capture; counting creepy crawlies to assess the health of the natural area; testing the filtration properties of the soil. The weather was glorious and we collected tons of data that will help the scientific work that Earthwatch is doing at the 300 tiny forests around the country.
