For bone health, we recommend two types of exercise: weight-bearing and strength training.
Weight-bearing exercise are exercised that help to bulid and maintain bone density. These exercises include activities that make you move against gravity while being upright, such as fast walking, running stair clinmbing and playing soccer. While great, bike riding is not a form of exercise that likely helps to improve bone mass.
Strength-training exercises or resistence training are exercises that additionally help to build and maintain bone density. These exercises include lifting weights, using elastic exercise bands, weight machings or lifting your own body weight. Curves (although there may be some weight bearing type exercises in this program) from my understanding may be more of this type of exercise.
I would suggest focusing on doing these types of exercise and continue your medication as prescribed. You need to consume 1200-1500mg of calcium per day. 600-1000 units of Vitamin D per day.
