calorie deficit

hope this is the correct place to ask

i've been BB benching 67.5kg the other day. right shoulder feels kinda funny. there was a slight pain but din bother bout it. was benching 70kg today and the pain starts to develop. i couldn't finish my 2nd set when the pain became more pronounced. when i do the bench press motion, there is a "clak" sound in my shoulder.

so should i deload? or stop for a period till it recovers?

How much cardio were you doing when you were not cutting?

since you wanna cut, try increasing the number of days per week you do your cardio first. gradually. only add in, if you hit a plateau.
When you plateau at 7 days, try doing 2 cardio sessions per day. that's gonna be a shock to your body for sure.

I thought you said 20 b4 this?
Stick to 20mins and 4 days(1 day increment from ur current cardio routine ) first. when there's no change in weight, then add another day.
Control your environment. I had classes from 8am to 8 pm and I had to cycle my ass back and forth. But I made sure I did my cardio in morning and I did my cardio in my evening. It's about how bad you want it mate.

When your cardio reached 7 days for 20 minutes/day. Add in sessions in the evening then. Then it'll be 14 cardio sessions a week. All in all, you WILL hit a plateau even at this stage, that's when you put in additional 5 minutes per session.

Nevertheless mate, you have to keep tabs on your diet. How much you're gonna lose depends on how much you've got to lose. How much can you lose from your change in routine/diet, depends on how much change you have in your routine/diet.

Say you're eating 2 cups of rice per meal,cut it down to 1 and half cup when you plateau, when that fails, cut it down to 1 cup. I try to stay clear of less than 3/4 of a cup.

Note* - Check every week if you lose weight,look in the mirror, see if there's changes. If you add in the extra cardio for that week, dont cut your amount of food intake, if you cut down your food intake, dont add in your cardio. Make little adjustments here and there. It's all about trial and error and making minor adjustments.

How long you plan to cut and how much you wanna cut anyway?

yes, i am a student. find out how much your daily macronutrients needs are and try slowly deducting fats and carbs from them.
