Measure
Control
Women randomized to the control group will receive calcium and vitamin D intake for 12 months. Calcium intake will be determined by analyzing 3 day dietary intake of calcium at baseline and then prescribing calcium carbonate supplements to ensure women have \~1200 mg of calcium daily. Vitamin D intake will be determined using baseline measures of Serum 25 (OH) D. Subjects who have serum D levels of 30 ng/ml or greater will be prescribed 1,000 IU vitamin D3 daily; subjects with levels of 20-29 ng/ml will be prescribed 2,000 IU Vitamin D3; and subjects with levels of 10-19 ng/ml will be prescribed 3,000 IU Vitamin D3. Calcium Carbonate: Used as daily supplement to ensure subject obtains 1200 mg of calcium per day (diet + supplement) Vitamin D3: Subjects will receive Vitamin D3 supplements to ensure serum level of Vitamin D is at least 30 ng/ml.
Risedronate
Subjects in the risedronate group will take 35 mg of the bisphosphonate "risedronate" weekly for 12 months plus CaD. They will be asked to follow the protocol for administration of risedronate including taking the medication upon arising in the morning with an 8 ounce glass of water, remaining upright for at least 30 minutes, and having no oral intake except water for at least 30 minutes. Calcium Carbonate: Used as daily supplement to ensure subject obtains 1200 mg of calcium per day (diet + supplement) Vitamin D3: Subjects will receive Vitamin D3 supplements to ensure serum level of Vitamin D is at least 30 ng/ml. Risedronate: Risedronate 35 mg orally will be ingested weekly by subjects in Risedronate group.
Exercise
Subjects in the exercise group will participate in bone-loading exercises three times weekly in addition to taking CaD for 12 months. Women will exercise at community Young Men's Christian Association's fitness centers (YMCA) and exercises will be monitored by on-site Exercise Trainers. Exercises will consist of high-impact weight-bearing exercises (jogging with weighted vests) and resistance exercises for upper and lower extremities. Progressive increases in weight loads will be prescribed to provide maximal strength gains. Calcium Carbonate: Used as daily supplement to ensure subject obtains 1200 mg of calcium per day (diet + supplement) Vitamin D3: Subjects will receive Vitamin D3 supplements to ensure serum level of Vitamin D is at least 30 ng/ml. Bone-loading exercises: Subjects will participate in bone loading exercises (weight-bearing and resistance) three times weekly at community YMCAs.

SECONDARY outcome

Timeframe: Baseline, 6, 12 months

Population: Intention to treat for persons who had valid data at baseline

Bone turnover is the process of removing old bone (resorption by osteoclasts) and replacing it with new bone (formation by osteoblasts). Menopause results in a brief period (\~5 years) of accelerated turnover with resorption far exceeding formation. In this study, resorption will be measured by Serum NTx.
