It's not always easy to take the plunge and try something new, which is why we should say a massive welcome and well done to Matt, Kate, Vicki and Jess who all made their GoodGym debut last night. Give them a cheer!

A hat tip also goes to all our park runners who raced on Saturday - if you haven't heard of them these are a series of free, timed 5k runs all over London which are super fun and great for improving your speed, ask if you have any questions! - and to Jack who did a 10k race on the weekend.

We kicked off the night with a nice, meaty session of dynamic warm ups. We also found out what everybody's super power of choice. As suspected, to be able to fly was top of the list, but we also had a lot of people wanting to breathe underwater, to have selective invisibility and to be able to teleport. We had a couple wanting 'Bernard's watch', but the prize goes to Emily, who would cleverly choose to be able to nab everybody's super powers in one go. Of course!

Tonight we had a respite from the heat of last week, thank goodness, and a nice 2k run down to Alderbrook primary school in Balham. We took a shortcut across the common, and with Will doing a bit of extra work figuring out where the entrance to the school was, we arrived in no time at all.

We were greeted by Linda, who led us to the three areas that needed painting. It was all really helpfully already set up for us, with piles of paintbrushes, sheets and buckets of paint ready and waiting. We divided up into three teams and set about giving the walls a lick of white paint. With 40 pairs of hands - that's 80 hands and no less than 400 fingers (don't even start with the whole 'a thumb is a finger but a finger is not a thumb thing') people - we got the job done in less than half an hour. Just enough time for Sophie, Luke and Alex to play the bat/bongo/music thing outside, and for Sarah, Jo and Matthew to give the climbing frame a go. A jolly good time was had by all.

We sprinted back up the hill to the common, where we found a nice little spot for our fitness session. This week we were attempting the 7-minute work out, which features all manner of exercises including jumping jacks, planks, press ups, high knees, and a whole squat-load more. Then we gave Will's military challenge ago, seeing how many press ups we could do in a minute. So tough!

Session smashed, all that was left was a quick run back to the BAC, with the Wandsworth playlist as our soundtrack, and a few stretches. What a group, what a night. Same again next week?
