In 2019 I had the opportunity to train at a center here in Barcelona (GlobalPerformance) that specialises in isoinertial training methodology and equipment. It was the first time I did this type of training so I took some notes.

This is a type of training originally developed for outer space use since it doesn’t rely on gravity as the traditional weight machines do.

In the video below, you can observe some exercises that can be done with the pulleys and flywheels used in this type of training.

The nice thing is that the machines could be attached with a monitor that took note of each concentric vs eccentric movement of my muscles and measured the variation between them. In just one session I was able to observe the weak points of my body and that gave me a very good indication of what I need to be working on for gaining further strength while at the same time preventing injury.

This type of training is excellent for tennis and padel training as there’s a lot of emphasis on correct posture and using the whole kinetic chain effectively for every movement, and this can transfer very well to our oncourt performance.

When you buy spectacles/glasses it’s important to buy the right fit, style and color for your face. Most of the times when you visit shops the attendants won’t really give you any assistance about the matter, and I really hate visiting spectacles shops in general.

All they do is stand behind you and make you uncomfortable, and at best they’ll just say that all the pairs you try look good. Anyway, I figured out that the best way to shop for spectacles is online, so that’s how I’ve been doing it for the past few years.

If you want to really learn how you should choose your spectacles, visit this excellent guide:

• Eyeglasses frames and face shapes

The shops I use in Spain are SmartBuyGlasses, Blickers, Bluenty and Mister Spex. The latter lets you order 4 pairs to try at home. All you need to do is return them within ten days and either choose one or just order another 4 to try out. Once you found the right pair, you can then order the custom lenses and they’ll send you the final pair in a few days.

Which Lenses to Order?

Lenses can be much more expensive than the frame, depending on what degree of short-sightedness you are correcting and how thin you want the lenses to be.

A good shop will be able to simulate how different lens thicknesses will look on your specific frame, generating a 3d model for you that is really helpful to visualize whether going for the next level of thinness makes sense or not.

It’s important to choose the right brand of lenses for your spectacles. I order Zeiss, Hoya or Essilor, which are the leading brands.

Zeiss

Zeiss is a German-based company known for its high-quality optics and precision. They offer a range of single-vision lenses for myopia, including:

• Zeiss SmartLife Single Vision: Designed for digital device users, these lenses help reduce eye strain and provide clear and comfortable vision throughout the day.

Extras to consider with Zeiss lenses:

• DuraVision BlueProtect: A coating that protects your eyes from harmful blue light emitted by digital devices.
• DuraVision Platinum: An anti-reflective coating that reduces glare, repels dirt, and resists scratches.

• Crizal Sapphire 360: A premium anti-reflective coating that reduces glare, resists scratches, and repels dirt and smudges.

A Note on Extras

As a heavy computer device user, I had looked into whether blue light coatings are of any use. They can easily double the cost of a prescription lens however there is no evidence that they actually help. The best thing you can do to help your eye comfort is to stop using electronic devices 1-2 hours before going to bed or use software like Flux to reduce the harsh light from devices when you are preparing to sleep.

There is no evidence that blue light harms the retina. I have therefore not bothered with blue light coating.

There are many misconceptions around Cholesterol that I want to tackle in this post. I have inherited high cholesterol levels and so I have a personal interest in the subject.

Typically doctors tell me that I need to eat healthy; as if I don’t already do so as an athlete. I understand that many people have unhealthy diets that worsen pre-existing conditions or even lead to specific conditions, but when you have a healthy athlete in front of you, dishing out generic advise like that is a bit nonsensical.

What is Cholesterol?

Cholesterol is a waxy, fat-like substance that humans need to survive. Your body makes cholesterol and absorbs it from the foods you eat.

When people talk about cholesterol in relation to heart health, they usually aren’t talking about cholesterol itself.

They are actually referring to the structures that carry cholesterol in the bloodstream. These are called lipoproteins.

Lipoproteins are made of fat (lipid) on the inside and protein on the outside.

There are several kinds of lipoproteins, but the two most relevant to heart health are low-density lipoprotein (LDL) and high-density lipoprotein (HDL).
