Looking to do some more cardio work but most things are boring and its hard to be motivated to continue doing them so considering heavy bag work. I've got wraps and gloves, did muay thai for a year but this was probably 5 years ago so my questions are... Is it a good idea concerning technique? As its hard to break bad habits and can anyone recommend certain channels/sites? Happy to start with complete basics in boxing/kickboxing and probably better to go that way. Any other info most welcome and thank you in advance!
