We need to clarify some terms. "Extension" means movement of a joint which increases the angle between two body parts. So elbow extension is the movement that increases the angle between the humerus and radius/ulna, i.e. straightening the elbow. The opposite of extension is "flexion", which is a movement of a joint which decreases the ...

If the question is really, "do I have to lift heavy weights", then the answer is "no", and I, the designated random person on the internet, give you permission not to lift heavy weights. If the question is "is heavy lifting overrated" or "doesn't heavy lifting suffer from these drawbacks", the answer to both is kind of ...

Yes, full range of motion resistance training can increase flexibility. Morton, S. K., Whitehead, J. R., Brinkert, R. H., & Caine, D. J. (2011). Resistance Training vs. Static Stretching: Effects on Flexibility and Strength. Journal of Strength and Conditioning Research, 25(12), 3391–3398. https://doi.org/10.1519/jsc.0b013e31821624aa Leite, T. B., Costa, ...

An efficient squatter mainly uses the glutes to extend the hips, not the hamstrings. As can be seen from this image the hamstrings crosses both the hip and knee joint: They therefore have two functions: extending the hips and flexing the knee. If you use the hamstrings to extend the hips in the squat you also get a flexing torque at the knee. This means ...

TLDR Mostly history, but also, depending on what you do, you may need space for bearings/bushings. History Once upon a time, weightlifting was new and the quality of steel you could get wasn't that great, especially when you needed hundreds of pounds of it. The Victorian weightlifters didn't buy those cartoon, fixed weight, globe-end bars because they hated ...

All resistance exercise involves forces being applied to the body in two distinct positions, with the forces acting in opposite directions. In any standing weighted exercise (squat, overhead pressing, deadlifts, etc), there is a downward force applied to the body by the weight, and an opposing upward force applied to the soles of the feet by the floor. It's ...

It sounds like you're misusing the term "mobility". That usually refers to the range of motion that you can put a joint through, like a dynamic (moving) type of flexibility. What you're describing ("using my muscles in various angles and different movements") is "exercise variation". Your idea basically seems to be doing ...

I think the question needs further refinement. Is sugar the enemy of what? Health? Gains? Weight-loss? Sugar alone won’t cause anyone to gain fat. A surplus of calories will cause people to gain fat. To that regard any macro including sugar would be detrimental to fat loss if it is consumed In a caloric load that is greater than your TDEE or maintenance ...
