Concentric movements involve muscles shortening to produce force. The lifting phase of exercises, standing up from a squat, and pushing a weight away from your body are all concentric actions. While these movements seem less dependent on flexibility than lengthening movements, adequate mobility significantly affects concentric performance. Research in the Journal of Strength and Conditioning Research demonstrates that joint range of motion affects force production during concentric contractions (PMID: 25144131). The researchers found that starting position, determined by flexibility, significantly influenced concentric power output. This article provides the mobility exercises that improve concentric movement capacity. Whether you struggle to generate power from deep positions, feel restricted during the lifting phase of exercises, or want to optimize your concentric training, these exercises address the underlying mobility needs. Understanding Concentric Movement Flexibility Demands Concentric force production depends on the position from which the muscle begins shortening. Deeper starting positions allow greater range for force application. A squat with full depth generates more total work during the concentric phase than a partial squat. Flexibility determines the positions you can access. Starting position also affects the stretch-shortening cycle. Muscles that begin from a stretched position store elastic energy that contributes to concentric force. Greater flexibility allows deeper stretch positions and more stored energy for the subsequent concentric action. A study in the European Journal of Applied Physiology found that flexibility affected concentric power production significantly (PMID: 24771367). Participants with greater range produced more force during the concentric phase of compound movements. Assessing Your Concentric Movement Flexibility Perform exercises through full range and note the position where your concentric phase begins. Compare this to your passive flexibility. If you cannot achieve the same depth actively that you can passively, mobility work will improve your starting positions. Next, test specific movements. Can you reach full squat depth before your concentric begins? Can you achieve full chest-to-bar position before pressing up? These observations identify flexibility limitations affecting concentric potential. Primary Mobility Exercises for Concentric Movements These exercises improve the range available for concentric starting positions. 1. Hip Flexor Stretch Why it matters: Hip flexor flexibility affects the starting position for hip-dominant concentric movements. Squats, lunges, and hip hinges all begin their concentric phase with hips flexed. Greater hip flexor length allows deeper starting positions. JME 113 Place one knee on your chair and move that knee both forward and back to feel a stretch in the front of your leg. 2. Seated Hamstring Stretch Why it matters: Hamstring flexibility affects hip hinge starting depth. Deeper hip hinge positions before the concentric deadlift phase increase the range through which force applies. Greater hamstring length supports superior concentric starting positions. JME 141 Sitting in your chair, extend one leg in front. Once extended, bend your upper body over that leg to fell a gentle stretch in your hamstring. Don't force anything - find what works for you. 3. Knee to Chest Why it matters: Hip flexion range determines squat depth. The deeper you can descend before beginning the concentric phase, the greater the range for force production. Hip flexion mobility directly affects concentric squat potential. JME 121 Sitting in your chair, grab onto one leg and pull it toward your chest for a gentle stretch. 4. Hip Circles Why it matters: Hip circles maintain comprehensive hip mobility. Concentric movements from various positions require hip freedom in multiple planes. Dynamic circumduction prepares the hips for varied concentric demands. JME 122 Keeping your feet in the same position, rotate your hips in a circle. Supporting Mobility Work Upper body and ankle mobility support concentric movements throughout the body. 5. Full Arm Circles Why it matters: Shoulder mobility affects pressing movement starting positions. The deeper the stretch position at the bottom of a press, the greater the concentric range. Arm circles maintain shoulder freedom for pressing movements. JME 44 Starting with your hand at the side, bring your arm up, over your head, then back down to the side. 6. Seated Thoracic Rotation Why it matters: Thoracic mobility affects posture during concentric lifting. Proper thoracic position supports optimal force production. Rotation work maintains the extension capacity that concentric exercises require. JME 150 Sitting in your chair, rotate your upper body both left and right. Don't do this too fast - find what works for you. 7. Calf Raise to Heel Rock Why it matters: Ankle mobility affects squat and lunge starting positions. Greater dorsiflexion allows deeper positions before the concentric phase begins. Dynamic ankle work maintains the range for lower body concentric movements. JME 232 Starting flat on your feet, rise to stand on your toes. Fall back down to your flat feet and then stand on your heels. This movement should be fluid and stable. 8. External Rotation at 90 Degrees Why it matters: Shoulder external rotation affects pressing positions. Adequate rotation allows optimal positioning for the concentric pressing phase. This rotation capacity supports force production during upper body pushing. JME 47 With your arms at a 90 degree angle, rotate them both up and down - keeping your shoulders in the same position. Programming Your Concentric Movement Flexibility Work Concentric movement flexibility improves with consistent practice. Use these guidelines: Pre-training: Dynamic mobility before concentric-focused training prepares the joints for deep starting positions. Move through full range to access positions from which concentric force will apply. Post-training: Static stretching after training maintains the range needed for effective starting positions. Focus on muscles trained concentrically to maintain their length. Progressive depth: As flexibility improves, access deeper starting positions for concentric work. Gradual progression allows the nervous system to adapt to producing force from new ranges. Common Mistakes in Concentric Movement Flexibility Work Several errors limit progress: Ignoring starting position: Many focus on the lifting itself while neglecting the depth from which it begins. Starting position flexibility affects total concentric work performed. Static stretching before heavy concentric work: Excessive static stretching reduces force production. Use dynamic mobility before training and save longer static holds for post-training. Limiting range despite flexibility: Some have adequate flexibility but do not use full range during training. Use the range you have to maximize concentric training benefit. Expected Timeline for Improvement Concentric movement flexibility improves gradually. Initial improvements in accessible starting positions appear within 2-3 weeks. Integration of new range into concentric training takes 4-6 weeks of combined flexibility and strength practice. Monitor your starting positions over time. Note improvements in the depth from which you begin concentric phases of exercises.
