Eccentric Leg Exercises: Using the Lowering Phase on Purpose

Start with the movement, not the slogan

In a squat, the descent is commonly an eccentric phase for several lower-body muscles. In a calf raise, lowering the heel is an eccentric phase of plantar-flexor work. The word describes a muscle action, not a special exercise category. It can be present in ordinary strength training when the lowering phase is controlled.

Compare the setup before you compare the exercise name

Tempo is useful because it makes the movement easier to observe. A two- or three-second lowering phase can reveal whether range and position stay consistent. It also changes the effort of the set. Do not assume slower is always better. A tempo should answer a training question, such as learning control, rather than becoming a ritual attached to every repetition.

A practical observation

Run a direct comparison on a light, familiar exercise. Complete six normal-speed bodyweight squats, rest, then complete six with a three-second descent. Write down range consistency and perceived effort, not just the burn. If the slower set forces a shallower range or hurried rise, reduce repetitions. The point is to choose a controllable task.

Build the session around the actual task

ACSM includes concentric and eccentric actions in resistance training and emphasizes individualized progression. That is particularly relevant when adding tempo, because the new demand may change what you can recover from. Keep the total work modest while you learn how a slower lowering phase fits your week.

Use a count that you can repeat

Count the lowering phase out loud at first: “one, two, three,” then rise normally. A count is a cue, not a metronome certification. If the last two repetitions lose the count, shorten the set before making the load heavier. This makes tempo a visible variable rather than an afterthought.

Illustrative example: Use two sets of six bodyweight split squats with a three-second lower, a light fingertip support, and a normal rise. Write down stance length and whether all six descents reached the same depth. On the next session, add one repetition per set only if the descent still looks identical. Do not add load and a longer lowering phase in the same step.

ACSM includes eccentric actions in conventional resistance training and recommends progression based on the trainee and goal. ACSM position stand Eccentric work is not a guarantee about soreness, athletic results, or injury. A controlled descent is simply a way to organize a resistance repetition. Pair it thoughtfully with demanding field, court, hill, or speed work.

Use tempo selectively. A three-second descent on every squat, hinge, and calf raise can turn a normal session into a different volume and fatigue problem. Pick one lift for the tempo block and keep the rest of the session ordinary. The next log entry should say which lift used the count and whether the planned range held. That small distinction lets you compare a tempo session with another tempo session, rather than confusing it with a normal-speed workout.
