But never fear, although gym doors may have closed on Thursday, there are still lots of opportunities to stay fit, healthy and motivated in and around Newcastle during lockdown.
Newcastle (in my slightly biased opinion) is one of the best cities in the UK to be a runner.
Ideally nestled between the rugged hills of the North Pennines and the wild and windy Northumberland Coastline, you simply can't run out of new and exciting places to explore.
In the city, Jesmond Dene, Town Moor and the Quayside boast some scenic routes for easy running. For sessions, City Stadium's gravel track is perfect when you want to pick up the pace.
A little further afield - although easily accessible by bike, metro or car - is Tynemouth, a quirky coastal town with a long beach and coastal footpath ideally suited for a relaxing afternoon run, and who knows, you may even spot one of the Tynemouth locals - a friendly Grey Seal.
If you are a keen hill runner (or just missing the stair climber in the gym), then Northumberland is the place to be. Steel Rig car park offers easy access to the well-signposted Hadrian's wall footpath and the beautiful town of Allendale is a great place to start a hilly exploration of the wild and windy North Pennines.
Missing your weekly spin class? Never fear, there are some great cycling routes in and around Newcastle.
If you are new to cycling, or just fancy a relaxing spin around the city, head to Town Moor, Exhibition Park or Jesmond Dene. These parks boast many miles of well-marked, traffic-free cycle routes that are a perfect alternative to the gym.
If you are keen to explore a little further, take a look at the following cycle routes in and around Newcastle.
Although the global pandemic has temporarily put a stop to long-distance cycle touring, all of these routes can be easily adapted for shorter day rides.
Broadly following Hadrian's wall, this 174-mile cycle route stretches from near Carlisle to Tynemouth. Not got time for the entire route? Simply hop on the well-marked cycle path and cruise from Newcastle to the beach in less than an hour.
Stretching between Newcastle and Edinburgh, this cycle route follows the breath-taking Northumberland coastline and takes in many attractions including the impressive Bamburgh castle and Lindisfarne Islands.
Kielder forest is home to some of England's best mountain biking trails. Marked according to ability, these trails are fun and well maintained. Alternatively, there is a 27-mile cycle path around Kielder Water and many shorter-distance routes are also available.
This mountain bike route stretches 120-miles from Berwick Upon Tweed to Hexham and is suitable for all abilities.
With gyms closed and many fitness classes put on hold, it would be easy to neglect your busy workout schedule. But never fear, there are many online opportunities to get your body moving.
While the studio is temporarily closed, Newcastle's Hotpod Yoga is streaming 45-minute yoga classes online for you to do at home.
From ballet to belly dance, Newcastle's Dance City is offering a wide range of dance and movement classes via Zoom.
Every Wednesday at 12pm, Runner's World host a live 40-minute workout on their instagram. So grab a water-bottle and be prepared to get very sweaty.
If you are lucky enough to have a stationary bike or rollers at home, take a look at Global Cycling Network's youtube channel and take part in one of their intense spin classes.
Disclaimer: due to the current COVID climate, long-distanced unnecessary travelling is highly unadvised. Perhaps refrain from any out-of-Newcastle journeys until these measures are relaxed.
