My fellow NYP junior, it is up to you if you want to do one at a time or do both work and exercise at the same time. I know I won't be able to do both at the same time. If have to choose one, best to focus on getting fit first in my opinion. Because when I was overweight and unfit, I get tired very easily. I also got cramps and backache from time to time because of it. Not sure if you are in the same situation but I'm pretty sure my body was in a pretty bad state. I was also in your shoes 2+ years ago. I was finishing my 2nd year of poly. BMI of 31.26, weighing 110.5kg at 188cm. Then I realized NS coming and my body was in a pretty bad state as like I said getting some ache and cramps so have to lose weight. So from there I started eating healthy and reduce the amount of food I eat. I focused on fixing my diet first before exercising as I was not fit at all. I could not even do a single proper pushup. Being fat makes me more lethargic as well. I didnt want to push myself too hard in terms of exercise because knowing myself I was worried that I will just give up. Afterwards losing a decent amount of weight, I slowly add in some exercises. I went to CMPB to get reassess and from pes BP got to B1. Then I went to sign on direct entry sergeant with SPF and managed to get in. I was still very unfit even when I went in. We did a trial IPPT almost 1 month inside training in HTA. I got single digit IPPT score with pushup, situp and 2.4km combined hahaha. But on the third official IPPT test on the third month, I managed to pass with IPPT score of 65. Now after posting out, my stamina and weight are going abit out of control again so I have to control and exercise once again hahaha.
