We're all behind Joe Wicks in his mammoth PE challenge for Children in Need.
If you want to support him with a text donation, you can do so - all the details are below and here.
As Joe reaches the end of his challenge tomorrow and raises money for BBC Children in Need (Fri 13 Nov), schools across the UK will be joining in for every burpee, squat and lunge!
Joe needs your help if he's to reach the 24-hour milestone. So dust off your gym shoes, find a sweatband, and get ready to workout tomorrow morning.
Although that's not to say you can't do a couple of star jumps now...
Joe needs to keep moving for a whole 24 hours, but he's also trying to conserve some of his energy – there's a long way to go!
So far he's had a full 20-minute HIIT workout, he's had an abs class, a stretching session, and he's been bouncing like a pinball between bike machines, cross-trainers and punchbags.
It's knackering to watch, so we can't imagine how he's feeling!
I love my sleep. I’ve got two babies so I like going to sleep early. I think it’s going to be mentally challenging at about 3am.
I kept waking up every hour last night, I had all this adrenaline in my body!
Lots of famous faces will be joining Joe Wicks for workouts throughout the day. Sam Smith’s already been on for some squats, Pussycatt Doll Kimberly Wyatt joined Joe (virtually) for some wind-down stretches, and now Paralympian Stephanie Reid is leading an abs class.

Maybe we’ll have to carry him home tomorrow. Or knowing Joe Wicks, maybe he’ll just run home tomorrow after the challenge!
Joe Wicks says the biggest hurdle of the next 24 hours will be doing PE on his own, without anybody else in the BBC's Radio Theatre.
So let's show him some support by joining in with our own bit of exercise.
Schools across the UK are already getting involved. St Thomas More in Hull joined in with the first workout!
And these guys are joining in with the 24 Hour Challenge.
He’s done star jumps, high knees, burpees, planks, boxing, squat-jumps. You name it – he’s done it. And it’s not even 10am. Just 23 and a half hours to go, Joe!
If you missed this intense workout, the next one starts at 12.10pm.
You can watch every single second of Joe's 24 Hour PE Challenge via the live video player above (refresh this page if you can't see it), as he tries to raise as much money as possible for Children In Need.

Exactly a year ago Radio 2's very own Rylan was embarking on his Ka-Ry-Oke Challenge for Children in Need - he's shared some words of support for Joe.
I’ll be doing five 20-minute live HIIT workouts, but I’m running, moving, boxing. I’m gonna be moving every 24 hours.
The only thing I can stop for is a five-minute break to maybe have a shower and some food!
Joe, also known as The Body Coach, has been a regular visitor to Radio 2 over the years, sharing his tips for healthy living and exercise.
Earlier this year, he made headlines as the nation's virtual PE teacher, leading home workouts that helped ensure kids (and parents) keep fit during lockdown - and keeping up the country's morale in the process.
He was recently awarded an MBE in the Queen’s Birthday Honours list, and has interviewed a range of top names, including Louis Theroux, Robin Arzón, Tim Peake, and Radio 2's Sounds of the 90s host Fearne Cotton for The Joe Wicks Podcast, available now on BBC Sounds.
You can also hear more from Joe in this episode of Desert Island Discs.
"So what better way to end it than by raising money for BBC Children in Need, a charity very close to my heart," he adds.
"Please show your support by donating whatever you can to this brilliant charity, and get involved by tuning in to work out with me and post your pictures on social media.”
Money raised will go towards supporting children and young people across the UK facing a range of disadvantages.
We'll be providing information on how to donate throughout the challenge, and you can find a 'Donate Online' link on this page.
