Exercise
High knees (raised knees) — a dynamic cardio exercise that mimics running in place with knees lifted as high as possible. It is one of the most effective warm-up exercises, activating the hip flexors, raising the heart rate and improving coordination. High knees is a standard warm-up element in many sports — from football to athletics.
🎯 Primary Muscles
Hip flexors, quadriceps, calves.
🔧 Secondary Muscles
Glutes, abs, shoulder and arm muscles.
⚡ Exercise Type
Cardio, dynamic warm-up exercise. Improves coordination.
📊 Difficulty Level
Light–moderate. Tempo can be adjusted according to fitness level.
📋 Proper Technique
1
Starting stance: Stand upright, feet hip-width apart. Arms bent at the elbows at a 90° angle, as when running.
2
First step: Lift one knee to hip height (thigh parallel to the floor). The opposite arm moves forward.
3
Alternating: Quickly lower the raised leg and lift the other. The movement should be explosive and rhythmic.
4
Arm action: Arms move in sync with the legs — right leg up = left arm forward and vice versa.
5
Posture: Torso vertical, chest lifted. Do not let the body lean back or forward.
6
Duration: For beginners 20–30 sec, advanced 45–60 sec. In HIIT format: 30 sec work / 15 sec rest.
💪 Muscles
| Muscle Group | Muscle | Role |
|---|---|---|
| Hip flexors | Iliopsoas, rectus femoris | Lifts knees upward |
| Thighs | Quadriceps | Leg extension and lowering |
| Calves | Gastrocnemius, soleus | Push-off force from the ground |
| Glutes | Gluteus maximus | Hip extension during the lowering phase |
| Torso | Abdominals | Torso stabilization |
| Heart | Cardiovascular system | Intense rhythmic cardio |
⚠️ Mistakes
- Knees too low: Thighs do not reach a horizontal position. The goal is knees to hip height.
- Torso leaning back: The body leans back. Solution: chest forward, torso braced.
- Knees not lifted: "Running" in place without lifting the knees. Consciously lift the knees.
- Looking down: The neck leans, disrupting posture. Look forward.
- Tempo too slow: The cardio benefit is lost. Maintain at least a moderate tempo.
🔄 Variations
| Variation | Description | Difficulty |
|---|---|---|
| Slow high knees | Slow, controlled tempo — more strength, less cardio. | Lightweight |
| Sprint high knees | Maximum speed. The most intense cardio variation. | Intermediate |
| With dumbbells | Light dumbbells held in the hands. Additional load for the upper body. | Intermediate |
| High knees with a jump | A jump is added every few steps. Higher intensity. | Hard |
