Physics of Weight Training – Explosive vs Grinding

Yesterday I have discussed the fundamental concepts to consider when analysing the physics of weight training – force, time (under tension, “TUT”), work, effort, and power – and have posited that two of them – force and effort – will be the main determinants of training impact, the former by influence how many muscle fibers are trained, and the latter by to which extent they will be (over-)trained.

Today I want to look more specifically at lifting weights, and what the difference is between lifting them very slowly, at moderate pace, and explosively. Continue reading

Physics of Weight Lifting – Fundamentals

I have recently read a post that argued that one should either lift ultra-slow, or as fast a possible, with everything in-between a waste of time (I will link it if I find it again). I would not normally argue that with someone twice my muscles mass and half my body fat, but his argument was based on physics, and I know one or two things about this, so I thought I’d describe this in a series of posts.

The Physics of Exercise – Climbing (stairs)

Second installment – an easy one: what about climbing (or, for most of us, climbing stairs)? Continue reading

The Physics of Exercise – Kettlebell Swing

I thought I’d post something fun today. Today I was wondering what the energy needs to some of the exercises were that I was doing, and I amused myself running the numbers on some of the exercises I was doing. Here the numbers on the kettlebell swing, the others will follow when I get a chance writing them down Continue reading
