As Insider's Senior fitness and nutrition reporter, I was invited to check out The Body Lab and its facilities.

The Body Lab offers a gym, as well as cutting-edge treatments, including hyperbaric oxygen therapy, cryotherapy, and a float tank.

Membership costs £4,950 ($6,800) to £16,000 ($21,800) a year, and the top tier memberships include unlimited use of the facilities (including personal training sessions), one nutritional consultation per month, and a quarterly biomarker analysis.

As I approached the building, the large glass door was opened for me, and I was welcomed in from the cold.

The entrance room is light, bright, and fresh thanks to the floor-to-ceiling windows.

The reception is home to a Modbar coffee bar. They were out of milk, but a staff member swiftly popped out to get some for me.

The lighting is designed to mimic the tones of the sun at all times of the day, thus keeping the body in its natural circadian rhythm.

The dots represent their three pillars: nutrition, personal training, and recovery therapies.

The interior design is slick and stylish, with marble counters, huge onyx wall light installations, and the same signature shade of brass everywhere from the water taps to the dumbbell screws.

The Body Lab has a Hyperbaric Hydroxy Airpod, which claims to speed up the body's healing process by increasing oxygen absorption by up to 35%.

I tried hyperbaric oxygen therapy for 45 minutes.

Some of The Body Lab's clients send emails or work on their laptops while inside the chamber, because it's easier to justify the time spent, Jacobs said.

I felt slightly lightheaded when I came out, but energized too.

Next, I went to try out the Body Lab's dual cryotherapy chamber.

I was given a vest top, shorts, ear-warmer, gloves, socks, and slippers to put on to prevent my extremities from getting too cold.

It was a new level of cold, but I managed the full two minutes.

While the cryotherapy and hyperbaric oxygen therapy are designed to energize, the Body Lab's float tank is for relaxation.

The Body Lab also has private medical rooms for massages, osteoporosis appointments, and blood work.

Downstairs in the Body Lab is the gym, where clients can workout on their own or with personal trainers.

The gym isn't huge but it's fitted out with brand new top-of-the-line equipment, mostly by the brands Atlantis and Prime.

The gym isn't huge but it's fitted out with brand new top-of-the-line equipment, mostly by the brands Atlantis and Prime.

There are dumbbells up to 60kg (132lbs), all of which have "The Body Lab" engraved as well as nuts and bolts in their trademark brass.

I tested some of the gym equipment and was impressed by how hi-tech it was.

At the end of the gym there's a red light room, which is for warming up prior to working out.

Inside there are red light panels and an exercise bike.

The Body Lab has a Fit3D body scanner, which gives people detailed reports on their body composition, posture, and other measurements.

Before and after training, members can get ready in the changing rooms.

The changing rooms are simple but stylish, each locker containing a robe, slippers, and towels.

The showers are spacious, stylish, and powerful.

Throughout the Body Lab, you'll find their own range of hand wash and lotion.

The changing room also has an infrared sauna, which I enjoyed for a few minutes.

I was impressed with the attention to data and detail at the Body Lab.
