Weight training is weird.

You would think, lifting all you can, as fast as you can would be the best.
But it is usually not.

Like, lift a certain weight until both sides of your body feels that it is equally light.
Like, lifting slow and smoothly often gives a better work out.
Like sometimes taking a week off can get you that gain after you plateaued. (and sometimes not)

For some, it is dumbbells, for other barbells, for other it is throwing heavy tires around that works.

I wish there was more weight lifting channels that actually covered the gamut and showed why certain things work for certain people, and what to detail for you.
