Grabbed one of these and they work really well.
I am measuring Upper bust, Chest, lower bust to keep track of cup size.
Then hips, waist and male belt line to track hips and exercise gains.
Bioelectric impedance scales are just about the worst for estimating body fat. The Navy formula is much better (just buy yourself a cloth tape measure or one of these kind of things) and measurement is super easy, barely an inconvenience. Calipers can be great, too, but I always had trouble getting consistent measurements at some of the skinfold spots.
There's also a cool online tool at bodywhat.com (they even have a sub at /r/bodywhat) but I think it's probably more accurate for people under 20%BF or so.
Glad you find it helpful! Yeah, unless you have one hell of a set of dumbbells you probably aren't pushing yourself enough. /r/homegym can probably give you good pointers on how to put together something that meets your needs. If you want I can lay out the compact low-cost olympic setup I used to have when we lived in the US.
Make sure you get your nutrition on point, too--target at least 1g/lb bodyweight of protein per day and keep your total calories below maintenance. You'll probably need to fine-tune your daily caloric intake so I'd recommend tracking your body weight and your waist (buy a cloth tape measure from a sewing/crafts store or one of these things from Amazon if you want to be fancy) every day in a spreadsheet.
r/intermittentfasting helped me with appetite control, and /r/fasting and /r/psmf got me through periods where I was frustrated/impatient with fat loss.
If you have questions or want pointers feel free to ask, as you can probably guess I have tons of advice (most of it sound, I think...)
