What muscles are worked during heavy bag?

[Beasting102]

i Know it works chest, core, triceps and legs. What about the back muscles? Traps, lats, rear delts?

I think it depends on your stance and what you do while whacking away at the bag

Shoulders. The stand out feature of a boxer's physique is the shoulders.

If I have not worked the heavy bag in a long time and then put in a good workout, my triceps and shoulders get the most sore a day or so later.
