A Pilates upper body workout can train much more than your arms. Reformer exercises can challenge the shoulders, chest, upper back, biceps, triceps, and core through pushing, pulling, weight-bearing, and rotational movements.
The springs provide external resistance, while the moving carriage and straps ask you to control the load through the full exercise. That makes the reformer useful for building strength and muscular endurance, especially when the workout includes enough challenge and progresses over time.
This guide explains how upper-body Pilates works, which exercises to include, how to choose resistance, and how to turn a collection of arm exercises into a balanced workout.
The reformer combines resistance with movement control, allowing a single exercise to challenge the arms, shoulder girdle, and trunk simultaneously.
During a seated row, for example, the upper back and elbow flexors pull the straps while the trunk resists being pulled forward. During a plank on the carriage, the shoulders support body weight while the core controls the moving platform. This integration is a defining feature of Pilates, but it does not mean isolated arm work has no value.
A 2026 American College of Sports Medicine position stand synthesized 137 reviews and concluded that progressive resistance training improves strength, muscle size, power, endurance, balance, and physical function. For a reformer program to serve as resistance training, it still needs progressive challenge and consistent practice.
These reformer exercises cover the major upper-body movement patterns and can be combined into one balanced session.
See, not that different at all and, dare we say, a bit more fun?
Alongside these core gym replacements, reformer Pilates can offer variations of pull-ups, rows, push-ups, and chest presses–just to name a few.
Use this sequence as a framework and adjust the springs, repetitions, and exercise versions to your experience.
These ranges are starting points, not rules. Stop a set when the technique changes noticeably or when you cannot control the carriage. A qualified instructor can help you choose variations that match your current strength and shoulder history.
The right spring setting creates a clear muscular challenge while allowing smooth, controlled movement.
More spring does not always mean a harder reformer exercise. In strap-based arm work, added spring tension usually increases the pulling or pressing demand. In exercises where the springs help return the carriage or support body weight, adding a spring may make the movement more manageable.
Use Flexia’s guide to adjusting reformer spring resistance to understand how support and resistance change from one exercise to another.
A useful setting should let you complete the intended range without jerking the straps, losing your trunk position, or gripping through the neck. The final repetitions should require attention and effort. If you could continue far beyond the planned set with the same speed and ease, the exercise may need more resistance or a harder variation.
Progress comes from gradually increasing the training demand while preserving a range you can control.
Change one variable at a time to determine whether the progression is appropriate. New exercises are not automatically better than familiar ones. Repeating key movements makes it easier to notice improvements in control, range, or resistance level.
Flexia users can also use Pilates metrics to track control, consistency, and speed during supported classes. Those measures provide useful movement feedback, while spring level, repetitions, and exercise variation show how the workload changes over time.
A useful Pilates upper body workout balances pressing, pulling, arm work, shoulder stability, and trunk control.
Start with exercises you can perform smoothly, choose springs that create a clear but manageable challenge, and repeat the key movements often enough to measure progress. Increase resistance, range of motion, volume, or exercise difficulty gradually.
Once the fundamentals feel reliable, an integrated exercise such as Snake on the Pilates reformer can add a more advanced shoulder-stability and core challenge. Build the prerequisite strength first, then learn complex exercises under qualified instruction.
A reformer can replace many familiar gym movements, but the most effective workout is not a list of substitutions. It is a balanced, progressive program that gives your upper body a reason to adapt.
