I've got fairly advanced Degenerative Joint Disease, so I use the various neoprene wraps for compression, heat retention, pain relief and "massage".
Back when I was active duty and wrestling with their idiotic "body-fat" measurements I'd use a pair of compression shorts to squeeze an extra coupla inches off my waist measurement when PT test season came.
I never was much on measuring my body dimensions, performance always meant more for me.
Any good sporting goods store should have a good selection.
