Moving up a weight class

[AdamGB]

i am currently lightweight at 62kg and 6ft which is way to light for my height and i don't like being this weight anymore.

I want to shift up to middleweight at around 72-75KG.

Will I have to enrol on a weight training program as i am thinking of taking a break from Thai boxing/boxing to do weights 3-4 times a week.

To move up in a healthy way, you have to adjust your diet, your gonna have to eat more.

Bingo, imo if you're 6 foot and walking around at 62kg your either young and still growing or not eating right...
