4 Hamstring Rehab Exercises to Rebuild Strength After a Strain.

Quick answer

Squat University walks through four rehab exercises — the hamstring bridge, single leg bridge with slider, single leg RDL, and Nordic curl — to rebuild the hamstring after a strain or tear, with exact hold times, tempos, and form cues for each.

Key takeaways

  • Squat University lists four rehab exercises to rebuild the hamstring after a strain or tear: the hamstring bridge, single leg bridge with slider, single leg RDL, and Nordic curl.
  • Keeping the knee straighter during a hamstring bridge shifts emphasis away from the glute and onto the hamstring, per Squat University.
  • The hamstring bridge progresses from a 5-second hold to a 10-second hold as strength improves.
  • The single leg bridge with a slider uses a 3-second eccentric knee-straightening phase to load the hamstring under lengthening tension.
  • Pointing the back toe straight down toward the ground during a single leg RDL limits pelvic twisting, according to Squat University.
  • The Nordic curl is highlighted as the knee dominant hamstring exercise in this rehab progression.

What exercises rebuild the hamstring after a strain or tear?

Squat University's rehab progression uses four exercises to rebuild the hamstring after a strain or tear: the hamstring bridge, the single leg bridge with a slider, the single leg RDL, and the Nordic curl. Each targets a different aspect of hamstring function — isometric strength, eccentric control, hip-dominant hinging, and knee-dominant curling — so the muscle is rebuilt through its full range rather than just one pattern.

  1. Hamstring bridge — isometric hold, knee kept straighter
  2. Single leg bridge with slider — eccentric knee extension under load
  3. Single leg RDL — hip dominant hinge pattern
  4. Nordic curl — knee dominant curl pattern

The creator opens the video by building a fake hamstring model out of Powerflex tape and an elastic band on the calf, using it to visually show how these exercises load the muscle during rehab.

How do you do a hamstring bridge to target the hamstring, not the glute?

Watch at 0:14

Keep the knee more straight rather than bent during a hamstring bridge to shift the workload from the glute onto the hamstring. This positioning change is the key detail — a bent-knee bridge biases the glutes, while straightening the knee forces the hamstring to do more of the work holding the bridge position.

  1. Set up in a bridge position with the knee straighter than usual
  2. Lift into the bridge and hold
  3. Start with a 5-second hold
  4. Progress over time to a 10-second hold as the hamstring gets stronger

What is the single leg bridge with a slider and why is it hard?

Watch at 0:25

The single leg bridge with a slider is a rehab exercise where one foot rests on a furniture slider so the knee can extend smoothly while the hip stays lifted. According to Squat University, it's very difficult when done slowly because the eccentric phase demands sustained control under load.

  1. Place the working foot on top of a furniture slider
  2. Bridge up into position
  3. Take 3 seconds to straighten out the knee, sliding the foot forward
  4. This creates an eccentric lengthening of the hamstring under load, which is why slow reps feel so much harder

How should you perform a single leg RDL and Nordic curl for hamstring rehab?

Watch at 0:36

The single leg RDL is the hip dominant hamstring exercise and the Nordic curl is the knee dominant one — together they cover both ways the hamstring functions. For the single leg RDL, lower under control with the back toe pointed straight down toward the ground; Squat University says this limits twisting of the pelvis during the hinge, keeping the movement clean and reducing compensation that can stress the healing hamstring.

Exercise Pattern Key cue
Single leg RDL Hip dominant Back toe pointed straight down to limit pelvic twist
Nordic curl Knee dominant Named as the knee-dominant finisher in the progression

The Nordic curl rounds out the progression as the knee-dominant movement, completing the rehab sequence after the hip-dominant and eccentric-focused exercises.

Frequently asked questions

What exercises help rebuild the hamstring after a strain or tear?

According to Squat University, four exercises help rebuild the hamstring after a strain or tear: the hamstring bridge, the single leg bridge with a slider, the single leg RDL, and the Nordic curl. Together they progress from isometric holds to eccentric loading and hip- and knee-dominant patterns to fully rebuild strength.

How do you do a hamstring bridge for hamstring rehab?

Perform a hamstring bridge by keeping the knee more straight rather than bent, which shifts the emphasis away from the glute and onto the hamstring. Squat University recommends starting with a 5-second hold at the top and progressing over time to a 10-second hold as the hamstring gets stronger.

What is the single leg bridge with a slider exercise?

The single leg bridge with a slider is a hamstring rehab exercise where one foot rests on a furniture slider. You bridge up into the position, then take 3 seconds to straighten the knee, creating an eccentric lengthening of the hamstring under load. Squat University notes it's a very difficult exercise when performed slowly.

What's the difference between a hip dominant and knee dominant hamstring exercise?

A hip dominant hamstring exercise, like the single leg RDL, targets the hamstring through hip hinging, while a knee dominant exercise, like the Nordic curl, works the hamstring through knee flexion. Squat University includes both in its rehab list so the hamstring is trained through its full range of function.

How do you perform a single leg RDL correctly for hamstring rehab?

To perform a single leg RDL, lower under control with your back toe pointed straight down toward the ground. Squat University explains this foot position limits twisting of the pelvis during the movement, keeping the hip hinge clean and reducing compensation while loading the hamstring.

How is a fake hamstring model made in the video?

Squat University makes a fake hamstring model by applying a base layer of Powerflex tape to the calf, securing an elastic band in place to represent the muscle, then wrapping a second layer of Powerflex over the top to hold everything together. This model is used to visually demonstrate hamstring anatomy and rehab exercises.

0:14Hamstring bridge (glute vs hamstring emphasis)

Here's 4 of those rehab exercises to rebuild your hamstrings after a strain or tear injury. The first is a hamstring bridge. By having the knee more straight versus bent, the emphasis is shifted from the glute and onto the hamstring. Start with a 5-second hold, progressing to 10 seconds.

The second exercise is a single leg bridge with a slider. The foot is on top of a furniture slider. You're going to come up into the bridge and then take 3 seconds to straighten out the knee. This provides an eccentric lengthening to the hamstring under load.

Very difficult exercise if done slowly. Exercise 3 is a hip dominant hamstring exercise, the single leg RDL. Make sure to lower under control with your back toe pointed straight down towards the ground so that you limit twisting of the pelvis. The last is the knee dominant hamstring exercise, the Nordic curl.
