How to Get in Shape After 40 (Even If It’s Been Years Since You Worked Out)
Let’s be honest. Hitting your 40s feels different. The mornings are stiffer, recovery takes longer, and the energy that used to come naturally now needs a little push. But here’s the truth: getting in shape after 40 isn’t about chasing your 25-year-old self. It’s about unlocking the stronger, wiser version that’s still in you.
You are not too old. You are not behind. You just need a smarter plan that fits the season of life you’re in now.
1. Your Body Changes After 40 and That’s Normal
Starting around age 30, adults lose about 3 to 5 percent of muscle mass per decade if they aren’t strength training. By 40, that loss can lead to slower metabolism, decreased energy, and more body fat.
But muscle loss is reversible. Regular resistance training can increase lean muscle mass by up to 10 percent in adults over 40, according to a study published in Sports Medicine.
At SOLDIERFIT, workouts are built around functional strength training, a combination of weight training, cardio, and mobility work that improves real-world performance. It’s not about fancy machines or endless reps. It’s about helping your body move, lift, and live better.
2. How to Stay Consistent When Motivation Fades
Everyone starts with motivation, but motivation is a spark, not fuel. The truth is, it always fades. What keeps people in shape after 40 isn’t motivation, it’s consistency.
A 2023 study published in the British Journal of Sports Medicine found that people who exercised at least three times per week were 60 percent more likely to maintain weight loss and fitness progress after one year than those who exercised sporadically. The difference wasn’t the type of workout, it was the routine.
So how do you stay consistent when life gets busy, stressful, or exhausting? You simplify.
Pick a schedule and treat it like an appointment. Don’t negotiate with yourself. Show up even on the days you don’t feel like it.
Find accountability. Training with others increases consistency by over 70 percent, according to the American Society of Exercise Physiologists.
Track small wins. Progress is addictive when you can see it. Strength gains, improved endurance, or even better sleep are all signs you’re winning.
That’s why community matters so much. At SOLDIERFIT, you’re surrounded by people who remind you that showing up is the hardest part, and you just did it. The more consistent you become, the more your body rewards you with energy, strength, and confidence.
3. Strength Training Is the Game-Changer After 40
After age 40, your body produces less testosterone and growth hormone, both of which are key for maintaining lean muscle and bone density.
Research from Harvard Health shows that adults who strength train at least twice a week reduce body fat by 7 percent on average while increasing lean mass and boosting metabolism.
Muscle isn’t just about looks, it’s your body’s armor against aging. It protects your joints, supports balance, and helps prevent falls and injuries.
The good news is you don’t have to lift heavy weights to get the benefits. At SOLDIERFIT, every movement can be scaled to your level. You’ll lift, move, and sweat safely under the guidance of certified coaches who make sure you build strength the right way.
4. Nutrition Doesn’t Have to Be Complicated
You don’t need to follow a fad diet to get results. You just need balance and structure.
A study from the American Journal of Clinical Nutrition found that people who eat 25 to 30 grams of protein per meal maintain more lean muscle and burn more calories throughout the day.
Focus on lean proteins, whole grains, fruits, and vegetables. Cut back on ultra-processed foods and sugary drinks.
And here’s the secret: consistency matters more than perfection. One bad meal won’t ruin your progress, but skipping your nutrition goals every weekend will slow it down.
Our trainers and coaches at SOLDIERFIT teach practical nutrition strategies that work in real life. You’ll learn how to eat for energy, recovery, and performance, not restriction.
5. Start Small, Stay Consistent
You don’t need to overhaul your life in a week. Start with three workouts per week.
Research published in The Lancet Public Health found that just 150 minutes of moderate exercise per week. That’s 30 minutes, five days a week that reduces the risk of early death by 31 percent and heart disease by 29 percent.
At SOLDIERFIT, each class is one hour long, built for busy adults who want results without wasting time.
Show up, work hard, and stay consistent. That’s it.
6. Progress Is Possible at Any Age
The National Institutes of Health found that adults who start exercising after 40 can improve cardiovascular health, flexibility, and muscle strength at nearly the same rate as those who started earlier in life.
It’s never too late. The human body is built to adapt.
If you’ve been inactive for years, your progress might actually come faster at first because your body responds strongly to new stimuli.
Every rep, every step, every class matters.
The Bottom Line
Getting in shape after 40 isn’t about going harder, it’s about going smarter.
Build strength. Eat clean most of the time. Recover well. And surround yourself with people who push you to stay accountable.
