This is the final part of a 3-part series on weight loss and aging. Part 1 talked about why weight loss is more difficult beyond 40 – metabolism slows down 5% per decade, lean muscle is lost, the hormonal landscape within the body is completely different, and all of the bad eating habits you picked up in your 20’s and 30’s start to catch up with you.
Part 2 discussed a few simple changes to your eating habits that can help overcome weight loss barriers. This article, Part 3, is about your exercise routine.
What follows are some general guidelines about how much you should be exercising, the kind of exercise you should be doing, and the exercise intensity you should strive for.
How much exercise do you need?
With age, exercise needs to compensate for decreased activity levels and a slower metabolism. Considering these two factors, a good goal is to exercise every day for a total of 2-5 hours per week, depending on your current fitness level. If you’re relatively inactive at the moment, start by walking 20 minutes per day and work your way upwards to an hour of exercise per day.
What kind of exercise should you be doing?
Sarcopenia – lean muscle loss with age – is a primary contributor to a slowing metabolism as you get older. Resistance exercise is your best weapon to combat sarcopenia and preserve lean muscle mass as you age.
Resistance exercise is the type of exercise that requires you to move your limbs against resistance. That resistance can take the form of your bodyweight (push ups), elastic bands (bicep curls), weighted bars (barbell bench press), or dumbbells (shoulder press). Resistance exercise should account for 50% of your total exercise.
Here are some good examples of resistance exercises to target your core (muscles in the area of the belly and the mid and lower back), your lower body, and your upper body:
- The plank
The plank is an exercise that activates the muscles of your deep inner core: the transverse abdominis, multifidus, diaphragm, and pelvic floor. These are the muscles that support and control your spine and pelvis.
To do a proper plank, start with your hands and knees on the floor. Then lower your elbows to the floor and step your feet back one at a time. Your elbows should be at 90 degrees and shoulder width apart. Your heels all the way up to the top of your head should be a straight line.
- The roll out
The roll out targets your entire core, including the ones in your lower back. It can be done with a dedicated roller, round dumbbells, a barbell, or a gym ball.
Kneel on the ground with the roller directly in front of you. Lean forward until the roller is directly beneath your shoulders. Engage your core. Roll forwards as far as you can without your upper body sagging. Then, roll back to the starting position.
Lower body exercises
- Body weight squat
The bodyweight squat utilizes the quads, the glutes, the calf muscles, and several muscles of the core.
Start standing straight up with your feet shoulder-width apart and your toes turned slightly outward. Slowly bend at the knees and hips to lower your body. Throughout the entire movement your heels should be flat on the floor. Keep moving downwards until your thighs are parallel to the floor.
- Stability ball hamstring bridge
The stability ball hamstring bridge primarily targets the glutes and the hamstrings.
Start lying flat on your back with your feet together, resting on the top center of a stability ball. Your knees and hips are bent at about 90 degrees in the resting position. The arms lie flat at your side pointing towards your feet. Keeping your arms on the floor and your back straight, squeeze your glutes to raise your hips off the floor. The aim is to create a straight line from your shoulder down to your knees. The knees stay bent 90 degrees throughout the exercise.
Upper body exercises
- The push up
A classic for a good reason. The push up is a multi-joint exercise that encourages core stability. A push up uses the abdominal muscles, the deltoids, the chest muscles, stabilizing muscles in the lower and mid back, the triceps, the forearms, and the biceps.
Start with your feet together and your hands shoulder width apart right beneath the shoulder joint. Your heels to the top of your head should form a straight line. Keeping your core engaged, bend at the elbows to lower your body down towards the ground. Keep going lower until your elbows are at a 90-degree angle and return to the top.
- The bent over row
The main muscles used during the bent over row are in the back, the latissimus dorsi, and the rhomboids.
A bent over row can be done with dumbbells, a barbell, or elastic bands. Holding the dumbbells with your palms facing down (pronated grip), bend your knees slightly and move your torso forward by bending at the waist. Keep going until your upper body is almost parallel to the floor and your arms hang perpendicular. The back should be completely flat throughout the entire exercise. Keeping the torso and the lower body stationary, lift the dumbbells toward your chest, bending the arms at the elbow. Hold at the top for a brief moment, then slowly lower the weights back towards the floor.
All resistance exercise should be light with a goal of 10-15 repetitions per movement.
