Eccentric training examples: 8 moves and how to do them

What is eccentric training?

Eccentric training emphasizes the part of a movement in which a working muscle lengthens while resisting an outside force. The American College of Sports Medicine describes everyday and exercise movements as combinations of concentric, or shortening, and eccentric, or lengthening, muscle actions.⁴ In a squat, the controlled descent is the eccentric phase for the knee and hip extensors; standing up is the concentric phase.

This does not mean every downward movement is eccentric for every muscle. In a pulldown, letting the handle travel upward lengthens the back and arm muscles that pulled it down. In an overhead press, bringing the weight from overhead toward the shoulders is the eccentric phase for the pressing muscles. Identify the muscle doing the braking, not merely the direction of the equipment.

Eccentric emphasis can take several forms. You can lower a familiar load with deliberate control, use assistance for the lifting phase and perform only the descent, or use equipment that applies more resistance during the lowering phase. The first option is the simplest for home practice. Eccentric-only and accentuated methods are more advanced because the lowering load can exceed what you can lift normally.

Do not assume that slower is always better. A 2025 systematic review and meta-analysis compared shorter and longer eccentric phases across nine studies and 166 participants. Its estimates for maximal strength and muscle growth were uncertain, although some subgroup results favored longer phases for strength in trained participants and volume-matched trials.² A controlled descent is useful for practice, but the evidence does not establish one universal tempo.

Which eccentric training examples can you try?

The following examples use ordinary bodyweight, dumbbell, barbell, or cable movements. The eccentric focus is the phase to control. The return method tells you how to begin the next repetition without turning every example into an eccentric-only drill.

These are movement maps, not prescriptions for a health condition. Start with a version you already know. MedlinePlus lists poor form, inadequate recovery, and doing an exercise that is too strenuous for your current fitness among common causes of exercise injuries.⁵ If a movement is new, its guidance recommends considering instruction to learn the basics.⁵

Bodyweight examples

For a push-up descent, begin at the top and lower as one unit. If you cannot press back up with the same setup, place your knees down before returning or use an elevated surface for the whole repetition. For a pull-up descent, reach the top with a stable step or suitable assistance, establish your grip, then lower without dropping. Stop the set when you can no longer control the descent.

For squats and calf raises, use support if balance limits control. The goal is not to stretch farther than your normal comfortable range. It is to resist gravity through a range you can manage. Keep the first exposure modest because unfamiliar eccentric work is the situation most associated with later soreness in the ACSM commentary.⁴

Weight and cable examples

In curls, presses, rows, and deadlifts, first choose a load you can move normally. Deliberately control the return rather than adding weight immediately. A cable can keep resistance connected through the return, making the lengthening phase easy to observe. A free weight still has an eccentric phase whenever the working muscles brake gravity.

How do you perform an eccentric rep step by step?

A useful first session is a demonstration, not a test of how much you can lower. The ACSM commentary says gradual increases in intensity and volume can minimize or prevent muscle damage from high-intensity eccentric contractions.⁴ MedlinePlus likewise advises pushing slowly and gradually and warns against increasing training days, duration, and difficulty at the same time.⁵

For a simple tempo demonstration, say “one, two” during the lowering phase and then return at your usual controlled speed. A 2019 systematic review described a fast but controlled eccentric duration of about two seconds as one potentially time-efficient method, while also saying evidence was insufficient for specific volume, effort, and frequency guidelines for advanced methods.⁷ This makes two seconds a practical counting example, not a proven ideal.⁷

Keep breathing rather than holding your breath through the whole repetition. Set up the area before starting so assistance, a step, or the resting position is ready. For a barbell exercise in which a failed repetition could trap you, use appropriate safety equipment or qualified supervision. MedlinePlus advises using equipment that fits, is in good working condition, and is used correctly.⁵

Does a slower lowering phase build more strength or muscle?

The short answer is that eccentric training can be effective, but merely stretching the lowering phase does not have a settled advantage for every outcome. In the 2025 review of eccentric phase duration, shorter phases improved countermovement jump height by a practically worthwhile amount with moderate certainty. Estimates for maximal strength and muscle growth were uncertain. Longer phases produced similar or higher strength gains in trained participants and volume-matched subgroup analyses, but the authors said more research was needed.²

A different question is whether training only eccentric actions outperforms training only concentric actions. A 2025 meta-analysis included 26 studies and 682 participants in its quantitative analysis. It found no statistical difference in imaging-based muscle growth between eccentric and concentric actions, and it rated the overall evidence very low.³ Some subgroups favored eccentric actions, but those subgroup findings do not overturn the uncertain overall result.³

An older 2009 review of 20 randomized controlled trials found larger total and eccentric strength gains when eccentric training used higher intensities than concentric training. It also found that gains were specific to movement speed and contraction mode. The authors linked the apparent advantage to the higher loads developed during eccentric contractions and called for more research on transfer to complex movement.¹

Together, the reviews argue against two shortcuts. First, a longer descent alone is not clearly superior for muscle growth. Second, comparisons become difficult when eccentric groups handle greater loads. If your aim is general fitness, consistency may matter more than an advanced method. ACSM's 2026 resistance training summary says regular participation is the primary goal and that advanced techniques are often optional for the average healthy adult.⁸

How can you measure eccentric training at home?

You do not need a laboratory to make your own sessions repeatable. At home, measure what you can directly observe: the exercise, load or bodyweight variation, repetitions completed, count used on the lowering phase, and whether each descent stayed controlled. These are training records, not measurements of muscle growth.

A phone video from the side can provide a demonstration check when the setup is safe and the camera does not obstruct the exercise. Review whether the first and last repetitions use a similar range and descent count. For a squat, compare the path and depth you chose. For a push-up, compare whether the torso stayed together. For a cable row, compare whether the torso moved to create momentum.

Count only controlled repetitions. If your planned “one, two” descent becomes a drop on repetition eight, record seven controlled repetitions rather than claiming eight identical reps. This turns control into something you can track without pretending that a stopwatch reveals muscle force.

Change one variable at a time. MedlinePlus specifically advises against increasing exercise frequency, duration, and difficulty simultaneously.⁵ You might first add a controlled repetition while keeping the load and count steady. On another week, you might adjust the load while keeping the repetition target and descent count unchanged. See progressive overload for a broader progression framework and sets and reps for tracking volume.

How should you read trends without overreacting to one workout?

Look across several comparable sessions rather than interpreting one unusually good or poor day. A useful trend is more controlled repetitions at the same setup, the same repetitions with a modestly harder setup, or steadier technique from first repetition to last. Keep the exercise and recording method consistent enough for the comparison to mean something.

Soreness is not a score for workout quality. The ACSM commentary states that high-intensity or high-volume eccentric contractions can cause delayed soreness and prolonged decreases in function, particularly when performed for the first time or infrequently.⁴ It also says gradual increases in intensity and volume can reduce that risk.⁴ A sudden spike in soreness after a new drill tells you the exposure was unfamiliar; it does not establish superior progress.

If normal performance falls while soreness accumulates, do not automatically add more eccentric volume. MedlinePlus notes that constant tiredness can signal overdoing exercise and that rest between workouts matters.⁵ Repeat the same modest dose only after normal movement feels restored, or step back to a simpler version.

The federal Physical Activity Guidelines place strength work inside a larger weekly routine. The Office of Disease Prevention and Health Promotion says adults need muscle-strengthening activity at least two days per week and 150 to 300 minutes of moderate-intensity aerobic activity per week for the most health benefits.⁶ Eccentric reps can be one method within those strength sessions, not a replacement for all movement.

What are the main mistakes and safety limits?

The first mistake is loading the descent beyond your ability to stop it. The second is using assistance to reach a top position without planning a safe exit. The third is adding eccentric emphasis to many exercises in the same first session. All three make it harder to follow the gradual approach recommended by ACSM and MedlinePlus.⁴⁵

• Do not use a chair, box, or step that can slide when setting up assisted pull-up descents.
• Do not catch a falling weight to rescue a repetition. Choose a load you can control through the planned range.
• Do not force a longer range solely because the exercise is labeled eccentric.
• Do not confuse next-day soreness with a requirement for progress.
• Do not increase load, repetitions, descent duration, and weekly sessions all at once.
• Do not continue an exercise that causes pain during the movement. MedlinePlus says to stop right away if pain occurs while exercising.⁵

If you have not been active or have a health condition, MedlinePlus advises speaking with your health care provider before beginning and asking which activities may suit you.⁵ A clinician or qualified exercise professional can also help adapt a movement when balance, a previous injury, or limited range makes the usual setup unsuitable.
