Answer:
Injuries due to falls are one of the most common household hazards. One out of five older adults who fall incurs a broken bone or a head injury. Wet floors, slippery stairs, and scattered toys all create the potential for falls. Ways to minimize risks: Make sure all staircases have solid handrails, securely affixed flooring, adequate lighting, and safety gates if there are small children in the home. The Regalo Easy Step Walk Thru Gate is adjustable to most spaces and easy to use, even with a baby in your arms. Keep all outside stairs clear of debris and hazards like ice and snow. Add secured mats, or grip tape to make surfaces less slippery. In 2015, there were more than 365,000 fires in US homes, causing everything from mild smoke damage to total devastation, including loss of life. Even candles or an unattended iron could lead to an accidental fire in your home, but there is a lot you can do to prevent a fire from getting out of hand. Ways to minimize risks: Install fire alarms on all levels of your home, and check and change the batteries at least annually. Consider investing in a smart smoke detector like Nest Protect. This alarm uses Wi-Fi to provide real-time updates and remote monitoring right on your smartphone or other mobile device.
Crunches
In my educated opinion, crunches would be the best choice out of these options to build strength. A one mile run builds cardio, sit and reach and gymnastics build flexibility and some strength, crunches is strictly abdominal strength.
