Title is self explanatory. Basically, I walk around at 76-78kg (183cm tall) and cut to 67kg with minor problems, such as a slight headache and a little weakness but come fight time I'm still able to perform 5x3min rounds (MT) w/o issues. My question is, would my performance be greatly affcted if I cut to 62? I know my kidneys would be bitching my ass off but would I like, "die" ? Been discussing with the guys at the gym and they argue I should do a test cut before actually going for it officially. The thing is, there is a 16man tourny coming up in 3 weeks and theres just not enough time for a test cut until then. I'm currently at 73.4kg 3 weeks out and figured it wouldnt hurt to ask for extra opinions. Thanks! PS: English is not my 1st language so I apologize for any possible grammar mistakes.
