How to Select the Right Weight for Each Lift
Tom Wigginton • May 9, 2025
Question: “How do I select a weight for an exercise, and when should I go up?”
We get this question literally several times every single day. And the answer isn't just “go heavier.” The answer is: it depends. Heavier is better—when heavier is appropriate. Sometimes you should go lighter and move faster. Sometimes you should go longer with the same weight. Sometimes you shouldn’t lift at all.
Smart weight selection is about clarity, context, and responsiveness. Here’s how we think through it:
1. Is the Movement High-Quality?
Before anything else, we ask: Are you doing the movement well?
This is Phase 3 work—movement mastery. If you’re still learning the pattern, ironing out inefficiencies, or rebuilding capacity post-injury, weight selection should support technical precision. That means:
- Moving in clean lines
- Feeling the right muscles
- Owning each rep from start to finish
Until that’s true, you don’t need more load—you need more intention. This is the base layer of every other training decision.
2. What Phase Are You In?
Once your movement quality is solid, we consult the broader training arc. Different phases call for different intensities:
- Phase 4–5: Strength Development
If your form is dialed in, the goal is simple: challenge your limits. If your top set feels strong, controlled, and maybe even easy—it’s time to increase the weight. Push toward the high end of your rep range with mechanical precision. - Phase 6: Power Development
Here, speed and explosiveness matter as much as weight. Ask:
Does the set feel crisp, snappy, and exhilarating?
If yes—but also underwhelming—go up. If it's sluggish or out of control, stay put or go down. The goal is maximum intent with total control. - Phase 7: Muscular Endurance
This is about sustaining effort with excellent form. Are you breaking too often during a set? That might signal you went too heavy. On the flip side:
Could you keep moving with perfect form and no breaks, even if the weight was higher? Go heavier next round. - Phase 8: Athletic Performance
Harder to pin down. This phase integrates multiple qualities: speed, strength, agility, and reactivity. Adjust loads based on how well you express intent. If you're moving like an athlete—fast, clean, powerful—you’re in the right zone.
- Phase 9: Conditioning
This is about metabolic intensity. The “right” weight is the one that drives your heart rate and breathing up while still allowing clean reps.
If you're recovering before the recovery window ends, your work wasn’t hard enough. Increase your tempo or your weight—or both.
3. How Ready Are You Today?
Now we take a step back. Training happens in the body you’ve brought with you today. Readiness can’t be guessed—it has to be sensed.
Factors to consider:
- Sleep — Did you get enough? Was it deep and restorative?
- Nutrition — Are you fueled or running on fumes?
- Alertness — Are you alert enough to do the work well? Would a caffeine boost or pre-workout drink fill the gaps? On the other hand, caffeine might mask fatigue, but it doesn’t fix under-recovery. Are you over-stimulated?
- HRV / Recovery Scores — If you track them, listen to them.
- Stress — Mental and emotional stress are real performance limiters.
- Focus — Are you sharp or distracted? Laser-focused or mentally elsewhere?
When readiness is high: lean in. When it’s low: pull back or shift your focus to tempo, technique, or skill work.
Training isn't just about pushing—it’s about adjusting the dial so that your body adapts and improves.
4. Now You Can Pick a Weight
After you’ve answered questions 1, 2 and 3, you’re finally ready to pick your loads.
Use the Rep Range as a Tool:
Much of our programming uses rep ranges like 8–12 or 5–8. Select a weight that:
- Challenges you at the low end
- Prevents you from easily hitting the high end
- Allows perfect, pain-free reps in the right muscle group
Example:
If your set calls for 8–12 Dumbbell Chest Presses:
- Set 1: 12 reps with ease? Too light.
- Set 2: Pick a weight you can do for 9–10 good reps, no more.
- Adjust from there.
When to Increase:
- You hit the top of your range cleanly? Go up on the next set (not next week).
- The set felt easy or underwhelming, even at full reps? Go up now.
You barely survived the set, and it got sloppy? Back off a bit.
The Bottom Line
Selecting the right weight isn’t just about effort—it’s about alignment. The right weight aligns with:
- Your current movement quality
- Your phase and training goal
- Your readiness today
- The stimulus you’re targeting
Go heavier when:
- You’re moving well
- The phase calls for intensity
- Readiness is high
- Lighter weights feel easy and unchallenging
Don’t go heavier when:
- Movement is messy or new
- You’re in a technical or recovery phase
- Your body isn’t ready to absorb the load
- You’re chasing numbers instead of adaptations
Training well means making good decisions. It means knowing when to push, when to hold, and when to pull back entirely. That’s not soft—it’s strategic.

How Vitruvian’s new partnership with DexaFit Denver helps you fight bone loss, build muscle, and personalize your fitness – starting with real data. Vitruvian Fitness has partnered with DexaFit Denver to bring you three powerful tools for assessing and improving your health: the DEXA Scan , VO₂ Max Test , and Resting Metabolic Rate (RMR) Test . These aren’t gimmicks – they’re scientifically backed ways to track meaningful progress in your training. If you're in your 40s, 50s, or 60s, you're at a turning point where training isn’t just about looking better – it’s about aging better . As the saying goes, “What gets measured gets managed.” And just because that’s a relic from my corporate past doesn’t make it any less true. Like your annual bloodwork, these tests give you a snapshot of important health markers that offer direction, motivation, and a baseline to measure progress against. Here’s what each test measures: DEXA Scan – bone density, lean body mass, and visceral fat VO₂ Max Test – cardiovascular fitness and aerobic efficiency Resting Metabolic Rate (RMR) – how many calories you burn at rest (your metabolic baseline)

How to create a cardio habit and turn it into a cardio lifestyle. We’ve talked about why cardio matters . You’ve got a handle on tr aining zones . And you’ve seen how we program your cardio training to maximize efficiency and results. But knowledge alone doesn’t build consistency. Cardio becomes the life-changing ingredient in your life when it becomes routine. So let’s talk about how to get started and how to make it stick —even if you don’t love it, even if your schedule is full, even if you’ve tried and failed before. This article is written mostly for the dabblers . The key is to get started, keep moving, and eventually create a new identity for yourself as someone who finds joy in their daily cardio habit. And to be clear, this isn’t about becoming a pro athlete. It’s about living longer, living better, protecting your independence as you age, and showing up for the future you want.
How to build a cardio plan that matches your goals—whether you're in it to win it or just want to feel 10 years younger. Nobody wants to rust out too early and yet, not everybody wants to race either. Most people fall somewhere in between. Maybe you’re not chasing a podium, but you are chasing longevity and quality of life. Or, maybe you’re not training for a triathlon, but you do like to enjoy a long hike without needing three days to recover. Or maybe you are chasing podiums, glory, and fame! In any case, that's great! In part 1 of this series, we talked about Why Cardio Matters . In part 2, we talked about gauging your effort levels by Decoding Your Training Zones . If you haven’t read those, you will find them helpful. Whether your goal is vitality , confidence , or competition , there’s a cardio plan that fits. The trick is structuring it smartly based on what your body needs and your life allows.
How you can train smarter to live longer, live better, and stay active and independent — maybe into your 90s or 100s. In our previous article, Why Cardio Matters , we talked about the benefits of doing cardio (like living longer) and introduced you to a few terms that might have been new: Zone 2, VO₂ Max, and lactate clearance. We also offered a general recommendation for how much cardio to do weekly. This article takes the next step: breaking down how the intensity you work at affects the benefits you get from each training session. The science of exercising is rich, complex, exciting, and overwhelming. Besides the fact that it is indeed complicated, it’s made worse by having acronyms for everything, buzzy catchphrases, and intimidating fitness personalities. This is where I’m going to try to make this easier to understand, convey why you should care, and encourage you to add cardio to your daily, weekly, monthly, seasonal lifestyles.
“Doing cardio.” What even does that mean? For some people, it’s hopping on the rower, bike, ski erg, treadmill, or elliptical and checking the box for however long Tom said to do it, then sneaking out before anyone asks questions. Others train for sanity. It helps manage stress, clear the mind, and release a flood of feel-good chemistry. Also in this category are people who actually just love to run, bike, swim, or play sportsball purely for the fun. And then there are those training for performance—to win races, set PRs, and push personal limits. All of this is cardio. And yet, when you zoom out and look at the data, it becomes clear that cardiovascular fitness does something that has a very measurable outcome: it extends your lifespan . And while we’ve all heard that cardio is good for your heart, most people don’t realize just how deep that benefit runs. And as in the case of so many other aspects of life, the broader public often benefits from the insights that trickle down from elite performance research. So whether you're reluctantly doing cardio or chasing a vibe, you’re tapping into the same physiological systems that turn podium-seekers into podium winners.
