Variable vs. Constant Resistance Training: What’s the difference?
How Each Resistance Method Works
Building on our overview, let's take a closer look at how each method operates.
Variable Resistance Training
Variable resistance training adjusts the resistance throughout an exercise to align with your body's natural strength curve. Unlike lifting a fixed weight, this approach modifies the load dynamically. For instance, when performing a bench press, the resistance decreases during weaker phases of the movement and increases during stronger phases, ensuring better muscle activation.
This technique often uses tools like resistance bands, chains, or specialized machines. Strength and conditioning expert Christian Bosse explains the difference between these tools:
"The resistance provided by chains is linear, whilst bands provide the resistance exponentially."
By tailoring the load to your strength at different points in the exercise, variable resistance training not only enhances muscle engagement but can also improve strength gains. Additionally, it may lower the risk of injury, making it a valuable option for rehabilitation.
Traditional Resistance Training
Traditional resistance training involves lifting a constant load throughout the entire movement. This method relies on tools like free weights, barbells, and weight machines, and it follows the principle of progressive overload - gradually increasing the resistance to challenge muscles and encourage growth.
However, biomechanics reveal a limitation: during traditional exercises, force output in the mid-range of the motion can drop to just 25–33% of your maximum strength capacity. A typical routine might include three weekly sessions, with each session featuring three sets of nine repetitions at 75% of your one-repetition maximum. Each phase of the movement - both lifting (concentric) and lowering (eccentric) - usually lasts about two seconds, with two-minute rest periods between sets. Because the resistance remains constant, certain parts of the movement may not fully challenge the muscles, leading to potential inefficiencies at "sticking points."
Despite these limitations, traditional resistance training remains a proven method for building strength and muscle mass, provided it incorporates proper technique and consistent application of progressive overload.

Equipment for Variable vs. Traditional Resistance
The type of equipment you use directly influences your workout technique and results. Each approach - variable or traditional resistance - utilizes different tools to apply resistance, and understanding these tools is crucial for tailoring your training effectively.
Variable Resistance Equipment
Variable resistance tools, like resistance bands, weightlifting chains, and cam-based machines, adjust the load dynamically to match your strength curve throughout the movement.
Resistance bands are lightweight, portable, and budget-friendly. They’re great for those on the go, but for serious strength and muscle-building, heavier bands are necessary to provide enough challenge.
Weightlifting chains add resistance as you lift. As more chain links rise off the ground, the load increases progressively. This makes them ideal for movements like squats and bench presses, though they’re best suited for vertical exercises.
Cam-based machines use specially designed wheels (cams) to vary resistance during an exercise. These machines, common in commercial gyms, offer smooth and controlled resistance. However, their fixed movement paths may not engage stabilizing muscles as effectively as bands or chains.
One major benefit of variable resistance equipment is its ability to align with your body’s natural strength curve, maximizing muscle activation at your strongest points during the movement.
Traditional Resistance Equipment
Traditional resistance tools provide a consistent load throughout the exercise. This category includes free weights, standard cable machines, and fixed-resistance gym machines, each offering unique advantages.
Free weights - like barbells, dumbbells, and kettlebells - are a cornerstone of strength training. They allow for unrestricted movement across all planes and engage stabilizing muscles effectively.
Standard cable machines use pulleys and weight stacks to deliver consistent resistance and support a wide variety of exercises.
Fixed-resistance gym machines come in two forms: selectorized machines with adjustable weight stacks and plate-loaded machines. Selectorized machines are beginner-friendly, offering easy weight adjustments and controlled movements. Plate-loaded machines, while requiring manual weight changes, can handle heavier loads and operate more smoothly.
Traditional resistance equipment excels at progressive overload, the gradual increase in resistance that drives strength and muscle gains. Its consistent load simplifies tracking progress and fine-tuning training intensity. However, because the resistance stays the same throughout the movement, certain phases may not challenge your muscles as much, potentially leading to sticking points.
Both variable and traditional resistance equipment have a place in a balanced training routine. Many fitness enthusiasts combine free weights with resistance bands to reap the benefits of both while minimizing their individual drawbacks.

Training Results: Comparing the Outcomes
Building on the mechanics discussed earlier, let’s dive into how each training method translates into results. Both variable resistance training (VRT) and traditional resistance training (TRT) can improve strength, but each comes with its own set of benefits depending on your fitness goals.
Variable Resistance Training Results
Variable resistance training adjusts the load throughout the movement, aligning with your muscles' changing ability to produce force at different points. This approach ensures greater muscle activation across the entire range of motion.
One of the standout benefits of VRT is its ability to reduce deceleration phases during exercises. For instance, during an 80% 1‑RM bench press, research shows that 52% of the upward movement involves deceleration. By minimizing this, VRT allows for higher mean power per repetition, especially when movements are performed with maximum effort.
Studies also suggest that VRT can be particularly effective depending on the individual’s training level. For trained individuals lifting loads above 80% of their 1‑RM, VRT tends to yield better strength gains. On the other hand, untrained individuals seem to benefit more from lighter loads (below 80% of 1‑RM). However, factors like body type and baseline strength can influence how effective VRT is, especially for exercises requiring significant force production, where traditional methods may sometimes be a better fit.
Traditional Resistance Training Results
Traditional resistance training, with its constant load throughout the movement, is a tried-and-true method for building foundational strength. This consistency makes it particularly effective for applying progressive overload.
A meta-analysis of 17 studies involving 491 participants found no significant differences between VRT and TRT when it comes to improving maximal muscle strength in both upper and lower body exercises (p = 0.46 for lower body, p = 0.14 for upper body). TRT is especially effective for building strength and muscle mass through structured programs involving progressive overload and high-repetition schemes. In some cases, TRT even outperformed VRT for lower body strength when more repetitions were included.
When it comes to muscle growth (hypertrophy), a review of 12 studies found similar improvements between VRT and TRT over short- to medium-term periods, with no significant differences between the two methods. The predictability of TRT makes it easier to track progress, plan workouts, and maintain proper technique, which is particularly helpful for beginners or those seeking a straightforward approach.
Ultimately, the best choice depends on your goals, experience, and what you want to achieve. Many effective training programs combine elements of both VRT and TRT to maximize results.
