Slowing the lowering phase of an exercise builds strength and supports tendons. How to do it safely after 40, with sets, tempo and cautions.
Eccentric training means slowing the lowering phase of an exercise, for example taking three to five seconds to sit down onto a chair. It builds strength effectively, improves control on stairs and slopes, and is a staple of tendon rehabilitation. It is not automatically gentler than other training, so introduce it gradually and keep it pain free.
What eccentric means
Every repetition has two phases. In the lifting phase (concentric) the muscle shortens, as when you stand up from a squat. In the lowering phase (eccentric) the muscle lengthens while it controls the load, as when you sit back down. Muscles can generate more force eccentrically than concentrically, so slow lowering puts a high, controlled demand on muscle and tendon.
Everyday life is full of eccentric work: descending stairs, stepping off a kerb, lowering yourself onto a low mamak stool, walking downhill at a hill park, or catching yourself when you trip. Good eccentric strength is the brake that keeps your knees and hips steady.
What the evidence says
- Strength and muscle. A meta-analysis comparing eccentric with concentric training in healthy adults found eccentric training produced favourable gains in eccentric strength, with no significant differences in concentric or isometric strength compared with concentric training. In other words, it is effective, but not magic.
- Older adults. A review of eccentric exercise in older adults found strength gains were the most consistent outcome, with functional capacity and body composition improving in older, frail and sedentary groups. It also found that muscle damage was avoided when new eccentric exercise was introduced gradually, and that the soreness response shrank with repeated sessions.
- Tendons. A randomised trial of 58 people with long-standing Achilles tendinopathy compared eccentric training with heavy slow resistance training for 12 weeks. Both improved pain and function, and the gains held at 52 weeks. Heavy slow resistance had slightly higher satisfaction and better adherence. The lesson is that slow, progressive loading helps tendons, and the exact method matters less than doing it consistently.
Eccentric training should therefore be one tool inside a strength programme, not the entire programme. The WHO advises muscle-strengthening activity on at least two days a week for all adults.
How to do it
Pick two or three exercises and add a slow lowering phase.
| Exercise | Lowering phase | Sets and reps |
|---|---|---|
| Sit-to-stand | Stand normally, lower to the chair over 3 to 5 seconds | 2 sets of 6 to 8 |
| Squat | Lower over 3 to 4 seconds, stand up at normal speed | 2 to 3 sets of 6 to 8 |
| Calf raise | Rise on both feet, lower slowly on one foot over 3 to 5 seconds | 2 sets of 8 to 10 |
| Step-down | Lower the heel to the floor over 3 to 4 seconds from a low step | 2 sets of 6 to 8 per leg |
| Wall or incline push-up | Lower the chest over 3 seconds, push up at normal speed | 2 sets of 8 to 10 |
| Band row return | Return slowly over 3 seconds | 2 sets of 10 |
Count the seconds out loud. Keep your breathing steady and avoid breath-holding. Do these sessions twice a week with at least 48 hours between sessions for the same muscle group, and add a small amount of load or one extra rep only when every set feels controlled.
Start small to manage soreness
Because eccentric work is a classic trigger of delayed muscle soreness, start with one or two sets of one or two exercises in the first week. Expect some tenderness for 24 to 72 hours. It usually fades faster each time. Our guide to muscle soreness after 50 explains what is normal and what is not.
Using eccentrics for knees, hips and tendons
- Knee pain on stairs. Slow step-downs and sit-to-stands train the quadriceps and hip muscles to control the knee. Use a pain-free range and hold a rail. See knee pain and keeping active.
- Achilles or calf tightness. Calf raises with a slow lowering phase are a common starting point. A common clinical rule is that mild discomfort during the exercise is acceptable if it settles within 24 hours, but sharp pain is a signal to stop.
- Hip and glute strength. Controlled lowering during bridges and hinge patterns builds support around the hip.
If you have a diagnosed tendinopathy, arthritis or a recent injury, work with a physiotherapist. The best programme depends on the tendon, the stage of the problem and your goals.
An 8-week progression
| Weeks | Focus | Example |
|---|---|---|
| 1 to 2 | Learn the tempo with bodyweight | Sit-to-stand, 1 to 2 sets of 6, lowering for 3 seconds |
| 3 to 4 | Add a set and a second exercise | Sit-to-stand and calf raise, 2 sets each |
| 5 to 6 | Lengthen the tempo or add light load | Lower for 4 to 5 seconds, or hold a light dumbbell or backpack |
| 7 to 8 | Progress one variable | Move to a step-down, or lower on one leg with a hand on a wall |
Reduce the load or the tempo if soreness lasts more than 3 days or if a joint feels sore afterwards. Keep your other strength work in place, since slow lowering alone does not cover every muscle group or movement pattern.
Is slower always better?
Not necessarily. For general strength, lifting at a controlled pace in both directions works well, and many people are served by a simple 2-second lift and 2 to 3-second lower. The Achilles tendon trial above suggests that heavy, slow lifting in both directions was as effective as eccentric-only training for tendon pain, with better adherence. So treat a slow lowering phase as a useful habit, not a rule. Choose the method you will actually keep doing, and make sure the load is heavy enough that the last two repetitions of each set feel challenging.
Eccentric emphasis is most useful when you want better control on stairs and slopes, when you are rebuilding after a tendon or knee problem, or when you need strength but find fast, jerky lifting uncomfortable. If your main goal is power, such as getting up quickly or reacting to a stumble, add power training once your strength base is solid.
Who should be cautious
Take extra care, and get advice first, if you have:
- A recent surgery, fracture or joint replacement.
- Uncontrolled high blood pressure or heart disease. Avoid breath-holding and very heavy loads.
- Osteoporosis with vertebral fracture risk. Avoid heavy spinal loading and forward bending under load.
- Statin-related muscle symptoms or unexplained muscle pain.
- Poor balance. Do eccentric steps and squats beside a counter or sturdy chair.
Stop and seek care for sudden sharp pain, a pop or snap, swelling, inability to bear weight, or chest pain, breathlessness or dizziness. A sudden pop at the back of the heel with weakness needs urgent medical review. In hot, humid weather, train indoors or in the cooler hours and keep fluids close.
Key takeaways
- Eccentric training means slowing the lowering phase of a lift, using about 3 to 5 seconds.
- It builds strength effectively, supports control on stairs and slopes, and is a useful part of tendon rehabilitation.
- Start with 2 to 3 sets of 6 to 10 reps on two or three exercises, twice a week, and build slowly.
- Expect extra soreness at first. Sharp pain, swelling or a pop needs assessment.
- Use it inside a full strength programme, and get advice for an existing tendon or joint problem.
