A few things… Without knowing your diet history, or how much weight you’ve lost in how much time, it’s pretty impossible to guess how long it will take to hit 10%. Like, if it took you a year to lose 10 lbs, that would lead to a very different answer than if you lost 40 in 6 months, right?
IF you’re actually losing a massive amount of strength while dieting, then you’re dieting wrong. That’s very likely considering you don’t seem to have a real diet plan and don’t count fats or carbs.
But I will also add that you didn’t lose the amount of strength you suggest you have in 2 weeks. To say that you lost so much muscle that you went from 225x10 to 205x8 in 2 weeks is flat out absurd. Not possible, unless you had been hospitalized for that 2 week period, and suffered from extraordinarily severe muscle atrophy. More likely would be that you had a bad day, or maybe you were tired from something else.
Guess I’ve wasted all of my time in the gym then… This is laughable. All I’ve ever done is strength-based routines. I think I look ok. Your problem is likely that you didn’t treat your accessory work like a bodybuilder, which is something I think all people training for strength should do.
If you just don’t want to do powerlifting stuff anymore, and just wanna look good, then cool. Do something else. But you’re telling yourself a lie if you blame that for not putting on the size you would like to have.
