💪 Double unders are more than just a faster version of a single skip. This article explains, in simple biomechanics, why they feel so much harder. We'll explore the FBD, GRF, impulse, and the SSC to understand why double unders increase both the mechanical load on your lower limbs & the physiolog...

🤣 First of all, I need to thank AI for making my ugly drawing into a more presentable & understandable picture. Addicted to sharing the biomechanics of the walking lunge, I am now presenting a quick overview of the basic push-up + its related forces. With understandable numbers, people can better...

Yesterday, a colleague of mine asked me this: “Is strength training alone enough for cardiovascular (CV) health?” This is a good question, because many people tend to choose one side. Some people only lift weights. Some people only do cardio. During my poly days, and even after my NS, I loved cv...

Is dragon boat really just about pulling harder? I used to be part of HP Singapore’s first dragon boat team in 2007, rowing in the Sg dragon boat scene. During our weekend training, especially when race day was getting nearer, we would always hear the coach shouting: “Hard drive!” “Insert yo...

Exercise is not a cure; it is primarily a means of prevention. Early prevention is essential to minimize the loss of muscle mass. When it comes to this prevention, cardiovascular training is crucial for maintaining good heart and lung function. Additionally, strength training is important to prepare your muscles for sudden movements, such as reaching for support when you fall, chasing after a bus, or standing up from your seat. These activities require a quick application of force, which is why resistance training is necessary to enhance the strength of your fast-twitch muscle fibers. I’m sharing this on LinkedIn to highlight the importance of exercise in maintaining overall health.

Why am I writing this? Recently, one of my S&C class students asked me a simple but important question: If the goal of my training is longevity, is it better to do cardiovascular training (CV) or resistance training (RT)? I thought it was a very good question, because many people tend to choose 1 si
