Which combo is easier to do and why?

[Monkey Turned Wolf136 1]

Let's talk about the 2nd.

With right leg forward, let's compare:

- right hook, left cross, and
- right jab, left hook.

When I throw

- right hook, my body rotate to my left. This makes my left cross starting point farther back (compress). This extra distance can help my left cross (release). My right hook helps my left cross.
- right jab, since my body is moving forward and not rotating, I need to change my forward momentum into body rotation. My right jab doesn't help my left hook.

A circular punch helps a straight punch. A straight punch doesn't help a circular punch.

In the 1st, the first jab doesn't help the 2nd jab (jab, jab don't flow smoothly). But right hook helps right back fist and right back fist help left uppercut (hook, back fist, uppercut flow smoothly).

I believe you are conflating two different combos. You initially posted "1. Right hook, left hook, right jab, left cross.". In there, you are never throwing a left cross after a right hook, but are instead throwing one after the right jab.

I believe you are conflating two different combos. You initially posted "1. Right hook, left hook, right jab, left cross.". In there, you are never throwing a left cross after a right hook, but are instead throwing one after the right jab.

I try to simplify the discussion by using 2 punches combo instead of using 4 punches combo. Sorry, this may cause a little confusion.

With right side forward,

1. Right hook, left hook, right jab, left cross - left hook helps right jab. Body rotation helps forward momentum.
2. Right jab, left cross, right hook, left hook - left cross doesn't help right hook. Forward momentum doesn't help body rotation.

Maybe it's just a personal thing. I feel more comfortable to change a circular punch into a straight punch. When my body is moving forward with a straight punch, I find it's not as comfortable for me to rotate my body.
