Why Do I Get Knee Pain During My First Deadlift Set?

Knee pain during your first deadlift set often feels stiff, tight, or unexpectedly sharp as you start pulling because the knee joint and surrounding tendons have not fully loosened up yet.

You might notice that your knees feel normal while setting up plates or moving around the gym, but the moment you begin your first deadlift set, something feels off. The knee may feel stiff at the bottom position, sore as the bar leaves the floor, or uncomfortable when you straighten up. Then, after a few sets, the pain fades or becomes much less noticeable.

That pattern often points to a warm-up and recovery issue rather than a sudden injury. If your knees are still carrying fatigue from previous training sessions or long periods of sitting before the workout, the first few loaded reps can feel rough. Once movement increases and the area loosens up, the knee may begin moving more comfortably.

The First Few Reps Feel Worse Than Everything After Them

You feel the pain right at the beginning, then it gradually settles down.

If your knee hurts most during the first set but improves during later sets, the area is often starting the workout feeling stiff and restricted. You may notice the knee feels rusty during the first few pulls and then moves more naturally as your body warms up. This is especially common around the patellar tendon and the front of the knee.

The Bottom Position Feels Tight Before The Lift Gets Going

You may feel discomfort while setting up or breaking the bar from the floor.

The deadlift starts from a bent-knee position, which can expose stiffness that is easy to ignore during normal walking. If your quads, hamstrings, or knee tendons are still tight from previous training, the knee may feel restricted before the lift even gets moving. Once several reps and sets are completed, that tight feeling often eases.

Managing Tissue Stress, Circulation, and Recovery

Pain that keeps returning during movement, after activity, or once the body cools down often means the injured tendons, ligaments, muscles, or nearby connective tissues are still recovering from repeated strain. When an area stays tight, restricted, or painful with normal movement, the tissues may not be moving or recovering as smoothly as they should.

Repeated stress can also leave circulation slower around the injured area, making it harder for oxygen, nutrients, and excess tissue fluids to move normally through the tissues. Over time, this can leave the area feeling stiff, weak, tight, or easier to aggravate during repeated movement and activity.

Topical Recovery Support

For acute injuries with pain, swelling and inflammation, some people apply Acute Sinew Liniment to help relieve pain, reduce swelling and inflammation, and increase blood flow to injured tissues to support faster recovery and a quicker return to activity. Some also use it alongside Sinew Herbal Ice to help speed up the recovery process and restore normal circulation and range of motion.

For ongoing pain, stiffness, or slow-healing areas after swelling and inflammation have subsided, some people apply Chronic Sinew Liniment to help relieve pain, stimulate circulation, and support recovery in overstretched tendons and ligaments. Some also pair it with Sinew Injury Poultice to further stimulate circulation and support deeper tissue recovery in areas with persistent pain and stiffness.

To warm up muscles, reduce tightness, and improve flexibility before or after activity, some people apply Sinew Sports Massage Oil to help increase circulation, prepare muscles for movement, relieve tightness, and support flexibility after activity.

Frequently Asked Questions

Why does my knee only hurt during my first deadlift set?

This often happens because the knee and surrounding muscles are still stiff and not fully warmed up when you begin lifting.

Is knee pain during the first set a sign of injury?

Not always. Pain that improves as you continue training is commonly related to stiffness or recovery issues, though persistent pain should be evaluated.

Why does the pain get better after a few sets?

Movement increases circulation and helps the joint and surrounding muscles move more freely, which often reduces stiffness.

Should I keep deadlifting if my knee hurts during warm-up sets?

Mild stiffness that improves may be manageable, but pain that worsens with each set should not be ignored.

Can previous leg workouts cause knee pain during deadlifts?

Yes. Residual soreness and fatigue from squats, lunges, or other leg training can make the knees feel more sensitive during the next workout.
