Testosterone, an essential precursor of estrogen in women, is made in the ovaries and adrenal glands. There is a steady decline in testosterone levels from the 20s through menopause. With surgical menopause, the level of testosterone drops precipitously. No clear lower limit of testosterone has been established; however 15 ng per dL ( nmol per L) commonly is used. One study 38 found that women with 0 to 10 ng per dL (0 to nmol per L) had markedly decreased sexual desire in all situations and absent or markedly decreased orgasms. Because of studies like this, supplemented with anecdotal evidence, many women have been started on testosterone therapy.
Having a kettlebell is essentially halfway to having all the exercise equipment you need. From swings to deadlifts, presses, cleans, snatches and goblet squats, grabbing a kettlebell can help you unlock a near-limitless amount of full-body exercises that can string together a monster HIIT workout.
