You can build and strengthen your bones with our OSTEO-GAINS Bone Health Program Year One. Proven for pre-menopausal women from 31-50 years of age to effectively stimulate bone to benefit your hips and lumbar spine over 52-weeks. The OSTEO-GAINS Bone Health Program Year One costs US$24.99 for 12-months access. No free trial is offered with the Bone Health Program. Once you download and register for the App, you get FREE access to the Pre-Conditioning Program and FREE access to the Stretching Program. Future access, e.g., Bone Health Year One or Bone Health Year Two, will require manual separate payments of US$24.99 for Year One or $28.99 for Year Two. Subscriptions do not auto-renew annually. ONE: Prepare Start with our OSTEO-GAINS Pre-Conditioning Program for the first 4 weeks. You will repeat each session (approximately 23-24.5 minutes) 3 times each week to get your body ready for the OSTEO-GAINS Bone Health Program. Complete the 12 sessions over one month before purchasing the OSTEO-GAINS Bone Health Program. TWO: Stretch Perform the OSTEO-GAINS Stretching Program (approximately 14-14.5 minutes) after every Pre-Conditioning session to help your muscles recover, or use the Stretching Program as often as you like. THREE: Perform The OSTEO-GAINS Bone Health Program Year One is performed barefooted on a firm and forgiving surface, such as carpet, grass, wooden floors or sand and works in 4-week blocks. You repeat the same session for 4 weeks before progressing to the next new 4-week block. The OSTEO-GAINS Bone Health Program Year One is designed to be progressive and repetitive. This program includes osteogenic exercises that take approximately 3-5 minutes a day, and you can do them in the comfort of your own home ... while you wait for the kettle to boil. In the OSTEO-GAINS Bone Health Program Year One, you will be guided through a structured exercise program that becomes progressively more difficult over 12-months. In the Bone Health Program Year One, you will 'Jump, Jump, Rest, Repeat' to strengthen your bones 2-5 times each week, using a series of specific jumps and jump-landings. Our research found that bone health in premenopausal women improved (3.5 to 5% at the end of 12-months) when they performed the exercises, taking only 3-5 minutes a day. Our research informed how we structured our 12-month OSTEO-GAINS Bone Health Program Year One. We measured improved compliance and technique, which led to significant lower body bone health improvements in our research participants. The OSTEO-GAINS Bone Health Programs are a supplementary osteogenic exercise program to specifically target bone health and can be performed alongside your regular exercise programs. PROGRESS Keep track of your landings/impacts progress over 52 weeks. DEXA Scan We recommend, where possible, getting a DEXA scan done before you start our OSTEO-GAINS Bone Health Program Year One. This will provide a benchmark measure of your current bone health and the ability to track any changes in your bone health over time.
