Personal trainers know their stuff, at least qualified ones do. Many people who hire a personal trainer do so because they aren't getting what they need from their work out, while others should hire one because they need to stay safe while they work out.
Hiring a personal trainer isn't a complex process and doesn't need to be a hassle. There are many great personal physical trainers in the Denver area who are qualified to work with adults of all ages, as well as ones who specialize in trainer those over the age of 55.
For you as a senior, it might be in your best interest to hire a personal trainer for both of these reasons. You want to be able to build and maintain muscle to support your joints and keep them strong, gently challenge your heart and lungs to keep them strong, and stimulate blood flow to all part of your body, including one of the most important parts of all – your brain.
You need a workout that will do this for you as much as possible, with the least amount of strain and impact that can do more harm than good, especially for seniors. You don't want to start a workout out that will cause you pain or injury.
You also don't need to work with a personal trainer every time you work out. You might choose to work with them for a few sessions, and go on your own with what the trainer has taught you. You also might just work with them once a week, or every 2 weeks, and go solo the rest of the time. As long as your doctor find this appropriate for your safety and well-being, you can go about this however you like.
Word of mouth is often the best way of finding a good personal trainer. As with all services, you don't want to pay for something that isn't going to to give you the help you need. You might have had a great plumber referred to you by a friend. The same goes for personal trainers. Your doctor might be the first person you ask. He or she might be able to point you in the right direction.
If you go to a gym, you should also be able to find a personal trainer who works there, or get referred to one from people who work at the gym. The Denver YMCA [http://www.denverymca.org/personal-training] on East Yale Avenue is great for people of all ages and should be able to help you find the personal trainer who can best meet your needs.
