Impact training can strengthen bones, but starting it at the wrong stage greatly increases your risk of injury.
Episode Summary:
Want the benefits of impact training without the injury? Impact exercises can be powerful for improving bone density, but they are also some of the most advanced movements you can do. They should only be added once you have a solid foundation of fitness. In this episode, I’ll show you the right way to train for better bones.
Show Notes:
Did you know that more than half of women in the United States over the age of 50 will be diagnosed with osteopenia, the precursor to osteoporosis? That is a staggering statistic. My mission is to help you protect the muscle you already have and then build more, because muscle is the most powerful tool you have for long term health. In my opinion, you can never have too much of it. Muscle not only makes you stronger but also strengthens your bones.
Here is the thing. There is a right time to start impact training and a wrong time. Done too early, the risk of injury skyrockets. Impact exercises create intense ground reaction forces that jolt your body and bones. Plyometrics are slightly different because they involve a stretch-shortening cycle where a muscle lengthens, then quickly reverses and shortens explosively. Both impact and plyometric training should only come after you have built full range of motion, joint stability, strength, endurance, and neuromuscular control.
Some experts recommend waiting until you can squat one and a half to two and a half times your bodyweight before beginning impact training. These are lofty numbers, and few women ever reach them. I am not trying to sound discouraging, but the reality is that if you are over 40 or 50, the wrong injury could follow you for life.
The good news is that there are smarter benchmarks. First, you should be able to walk a mile comfortably in under 15 minutes. Second, you need a consistent history of three strength workouts per week, each lasting at least an hour, for a minimum of six months. Third, you should be able to do walking lunges non stop for five minutes without soreness afterward. Fourth, you should squat with full range of motion, hips below knees, with at least 115 pounds for three sets of ten for six weeks straight. Finally, you should handle Bulgarian split squats for three sets of ten while holding 30 pounds of total weight.
If you can check those boxes, you are ready to move forward. Start slow. Slower than you think. The progression matters more than the speed. Heel drops, jumping jacks, jump rope, and squat jumps are excellent ways to begin. The goal is to expose your skeleton and spine to controlled impact, and the best results often come when barefoot on a hard surface.
When you move gradually and pass the strength benchmarks, you will not only be safe but you will be a powerhouse actively reversing osteopenia and building strong bones for life.
