4 weeks in and down 15lbs?? Damn.... I think you are being a little hard on yourself. I'm sure in another 8-12 weeks you will easily be where you want. I think you look solid bro, no homo.

I would do fasted cardio and cut carbs.

It's just diet man, you just gotta dig deep and diet down to say true 8-9% Dexa bodyfat. But ya, if your scans aren't helpful then just stick with the scale and the mirror. At that point you should be down to burning through the lower abs fat, well into your lower back fat, and if you keep pushing past that you'll head into the glutes which is often the last place to burn off.

A true hardcore cut deep into single digits bodyfat% can be humbling. First 2/3 of the cut you're just getting smaller and flatter. But once you crack into single digits then everything gets really good, REALLY GOOD... Then you get to see what you're really working with, you're true Lean Body Mass and the leaner you get in your cut the better your gains will be in the next growing phase.

Your gear looks fine for a cut. You should add a fat loss stack in though to get things moving much faster. Clen, T3, Slu-pp-332, Methylene Blue + Yohimbine/rauwolscine once your close to 8% BF. Also running GH year around will help you stay leaner. 45mins on the StepMill(StairMaster) 2x ED will speed things up and improve overall conditioning. Don't take this the wrong way but you can't even see abs at all in your pic, theres no way you're anywhere near single digits bodyfat% regardless of what any scan says. Hopefully you have better pics that show otherwise but based off these I have you 15-20% BF. And I know that's exactly what you're talking about here also. I know it's easy to get offended talking about bodyfat % but I'm just talking numbers here. No offense intended.

Just dig deep, diet harder, ramp the fat burners up. Double up on the cardio. And just keep going bro until you get there. You can do it. Just finished up my cut a month or so ago, White Fish like Cod/Talapia is a game changer for a deep cut, thins the skin, least amount of collagen in a protein. Talapia, Rice, Veggies, Water. Absolutely shredded/peeled to the bone in no time. Basically what you're looking for here is pretty much a true contest prep(minus the last 2 weeks). I'd personally bring your fats closer to zero so you can increase the carbs instead, you'll need those carbs, but that's me.

I struggle with this as well. I have an area around my lower back that just is stubborn and when I was overweight stretched the skin. I 100% want to share with you what I did and do. If it sounds like you want to try thats awesome, or cherry pick too. Its all good.

First off, the lower 2 photos are still double digits on body fat. Of course its being genralized, but the rib cage is visible front and sides very much so in sub 10%. Thats ok tho. Many times we think we have gone far enough but just havent. You have to keep going. And you could be watery but its hard to tell. Ive looked like shit before bed, like a swollen frog. Slept great, woke up pissed like a racing horse, and Im lean and dry.

Fasted cardio, preferably early in the morning, about 2 to 3 hours before you weight train. Minimum 3 times a week 20-30 mins a session with moderate heart rate.

Sauna daily if possible. Calms CNS, keeps water off, burns a little bit of fat.

Standing abb exercises, like boil makers (elbows to knees, hands behind head) Hoola hooping( not a joke) The idea is train abbs but keep them small and the waist from bulging with larger muscles. More resitance, more muscles, just need definition for abbs.

Maybe try Clen or an ECA stack if your healthy for it. Those work well and fast and synergistic with diet and cardio.

Make a fokd journal and try to discover the ones that make you bloatey. Certain foods like brown rice or oats, can bother peoples guts. Bloated guts is bad for cuts.

Keep cortisol lowww. Try to sleep as well and routine as possible, and stay chill.

Thats the stuff that works for me. Hope maybe some of it might for you.

A lot of the guy's on here just seem to use Reta when wanting to shift some bodyfat quickly.

Need more chest muscle to pop veins and separation

You might need to add some rest days and refeeds in there buddy. From what you described you are taxing the shit out of yourself. You gotta let your body know that you're not trying to kill it.

It's very hard to convince yourself on a cut that eating MORE will help you lose more body fat, but it is important to add a refeed in once a week where you're in a surplus for 24 hrs. It signals to your body that the famine is over and allows a reset.

Also lifting 7 days a week will likely yield an injury. Need rest days.

Also hgh is a hell of a thing for knocking off body fat.
