Why Do I Get Lower Back Pain On My First Deadlift Set?

Lower back pain during your first deadlift set often feels sharp, stiff, or tight as the bar leaves the floor because the lower back and surrounding muscles have not fully loosened up and prepared for the movement yet.

You may notice your back feels fine while walking around the gym, but the moment you start pulling the bar from the floor, something feels off. The first rep may feel stiff, the second uncomfortable, and then the area gradually loosens up as you continue lifting. That pattern is common when the lower back has not fully warmed up before heavier loading begins.

You might also notice the pain is worse after a long day of sitting, an early morning workout, or after several days away from training. The lower back muscles and hip muscles can feel restricted at the start of the session, making the first deadlift set feel much harder on the back than the sets that follow.

The Back Feels Locked Up As The Bar Leaves The Floor

You may feel the pain immediately during the first few reps.

The first pull often exposes stiffness that was not obvious while standing or walking. You might feel a sharp tightening sensation as you begin the lift, but then notice the movement becomes more comfortable once your body temperature rises and the muscles loosen.

The Pain Improves After Warming Up But Returns Next Workout

You may feel better later in the workout but repeat the same pattern every session.

If the lower back keeps hurting only during the first set, the area may still be carrying fatigue from previous training sessions. You might finish the workout feeling fine, only to notice the same stiffness and soreness return the next time you approach the bar.

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 lower back only hurt on the first deadlift set?

This often happens when the lower back and hips are still stiff at the start of the workout and loosen as you continue moving.

Is it normal for deadlift pain to improve after a few sets?

Mild stiffness that improves with warming up is common, but pain that is severe or worsening should be evaluated.

Can sitting all day make my first deadlift set hurt?

Yes. Long periods of sitting can leave the lower back and hips feeling tight, making the first few reps feel uncomfortable.

Should I stop deadlifting if my back hurts on the first set?

If the pain is sharp, worsening, or changes your movement, it is wise to stop and assess the problem before continuing.

Why does the pain keep coming back every workout?

The area may still be recovering from previous training, causing stiffness and pain to reappear at the start of each session.
