Vito, did the weight loss rate gradually taper off or was it an abrupt stop?
If you can, get your body fat % checked, you might be leaner than you realize.
Hydrostatic weighing is the gold standard. Skin-fold calipers can work but the person doing the test must be skilled and the more sites that are measured, the better the results.
The electronic scales/handheld units are only good for a ballpark estimate and can be off 1-2% points on either side.
You can try changing up the duration of exercise, alternate long/short days and build up to one extra long workout once a week.
