The aerobic energy system is a low power output energy system that offers a sustainable flow of energy over longer durations that its anaerobic brothers. As we discussed in the last blog post, the aerobic energy system starts to take over as the dominant Adenosine Triphosphate (ATP) producer as soon as any physical activity begins to take …
As seen in the image above, exercise style/emphasis ordering is our first and most important determining factor. Fatigue is half of the ordering equation, but it has the most influence over daily structure. Because effective resistance training programs require some form of cardio, we need to make sure that our sessions support concurrent (targeting more …
Doing the same things, the same way, every day can be harmful to our mental and physical health. Being comfortable as creatures of habit doesn’t do much to keep our brains healthy.

Another way to introduce postural variation into the office workplace is to implement a break policy that requires the worker to step away from the workstation periodically throughout the day, ideally every 20 to 30 min. Traditional breaks – two 15 min and one 30 min – are not sufficient to minimize discomfort at the …
There are two types of forces can impose loads on a tissue during work. External loads refer to those forces that are imposed on the body as a direct result of gravity acting on an object being lifted or manipulated by a person. However, in order to maintain equilibrium, this external force must be counteracted …
Building muscle mass can bring a plethora of benefits to both health and performance (not to mention looking better as a result) that many people aren’t even aware of.
