Most active guys hit their 40s and realize the days of heavy benching, occasional cardio, and weekend pickup games just won’t cut it anymore. Your strength takes a nosedive, recovery takes longer, and according to research, your fast-twitch muscle fibers (the ones responsible for explosive power) begin to deteriorate day by day.
Fortunately, you can combat this decline without resorting to high-impact, high-intensity exercises. Training methods like ‘contrast loading’ can help to bridge the gap between raw strength and explosive power.
The idea is simple: You pair a heavy, compound lift with a fast, bodyweight, or lightly loaded movement that mimics the same pattern. Whether you’re in your 40s, 50s, or beyond, the result is stronger muscles, quicker-firing motor units, and the ability to move like an athlete again.
Here’s how contrast loading works, why it’s so effective, and how to start using it to boost your strength and explosive power after 40.
What Is Contrast Loading?
Contrast loading involves pairing a heavy, compound lift with a light or bodyweight explosive movement that mimics the same pattern.
“Examples of contrast loading include doing a heavy squat followed by jump squats,” says James Brady, CPT, a certified personal trainer at OriGym. “The heavy lift primes your muscles so the following explosive movement feels more powerful.”
That “priming” effect is what gives contrast loading its edge. The heavy lift wakes up your nervous system, recruiting more muscle fibers than usual. When you immediately follow it with a lighter, faster move, those same fibers fire quicker and more efficiently, translating raw strength into usable power.

How Contrast Loading Works
What sets contrast loading apart is its neurological component. According to a 2024 study in the International Journal of Human Movement and Sports Sciences, contrast loading doesn’t just train your muscles; it also trains your nervous system to recruit and fire muscle fibers faster.
“When you lift heavy, your nervous system recruits more muscle fibers than usual,” Brady says. “By immediately following with an explosive move, you’re teaching those fibers to fire faster and more efficiently. It’s essentially rewiring your body to produce more force in less time.”
Studies show that incorporating contrast loading can result in increased strength, more explosive power, and faster reaction times without having to rely on high-impact plyometrics or sprints. That’s fantastic news for men in their 40s and beyond who want to train for speed and power without harming their joints.
“During a heavy lift, your muscles and nervous system get primed for maximal force output,” says James Bickerstaff, CPT, a certified personal trainer at OriGym. “The explosive move that follows takes advantage of that ‘primed’ state, allowing you to jump higher, throw harder, and lift heavier.”
How to Incorporate Contrast Loading
While contrast loading can be a valuable tool in your fitness arsenal, it shouldn’t be the mainstay of your workout routine.
“Contrast loading should be thought of as something additional, not the main workout,” says Brady. “Two to three pairings per workout, one to two times per week, is plenty. You should also place them early in your session when you’re fresh, and allow enough rest between supersets so power doesn’t drop off.”
The rest Brady mentions is essential for recovery during workouts. Unlike traditional supersets, where you rush from one exercise to the next, contrast loading requires short but deliberate breaks (around 30 to 90 seconds) when you go between heavy and explosive movements. That allows your nervous system time to reset before producing max force again.
“Due to its physical demand on the nervous system, it’s best used one to two times per week,” Bickerstaff recommends. “When it comes to the number of sets, research suggests two to four sets with one to five reps in each is the ideal program.”
Lower-Body Contrast Loading
- A1: Trap Bar Deadlift – 4×4 @ 80% 1RM
- A2: Jump Squat – 4×6 (bodyweight)
Upper-Body Contrast Loading
- A1: Bench Press – 4×3 @ 75–85% 1RM
- A2: Plyo Push-up – 4×5

What Exercises Work Best
You’ll get the most out of contrast loading by pairing movements that share the same pattern. That’s how you transfer the strength stimulus directly into explosive power.
“The best pairings match movement patterns such as bench press with explosive push-ups or deadlifts with broad jumps,” says Brady. “Avoid mismatched combos or complex moves if you’re tired like heavy overhead presses followed by handstand pushups as they carry more risk than reward.”
Here are a few tried-and-true contrast pairings that work, according to Bickerstaff:
- Trap Bar Deadlift + Jump Squat
- Front Squat + Kettlebell Swing
- Bench Press + Plyo Push-up
- Barbell Row + Medicine Ball Slam
- Split Squat + Jump Lunge
Alternative exercises that are easier on the joints and safer for older adults or those with knee or back issues include sled pushes, kettlebell swings, and medicine ball throws.
Who Should (and Shouldn’t) Use Contrast Loading
Contrast loading can benefit pretty much anyone, but it’s especially effective for men over 40 who want to stay strong, fast, and functional while reducing their injury risk in the gym.
“Anyone looking to build power, such as athletes, weekend warriors, or lifters in their 40s who want to stay athletic can benefit from this,” says Brady. “Those with joint issues, beginners, or people with poor lifting technique should be cautious, since the explosive element increases stress on the body.”
The Bottom Line
Contrast loading isn’t flashy, but it’s one of the simplest and most efficient ways to train like an athlete again. At its core, contrast loading involves combining heavy strength training exercises with fast, explosive movements. This approach will activate your nervous system, build power, and improve coordination with a reduced impact on your joints.
For men in their 40s and beyond, that might be the difference between just lifting weights and actually moving like an athlete again.
