Strength training breaks down muscle tissue, which can result in tightness and soreness afterward.

Compound lifts like squats, deadlifts, overhead press, and bench place load on multiple joints. When stabilizers fatigue, stress increases in the knees, hips, shoulders, elbows, and wrists.

Tight calves, hips, chest, shoulders, and limited thoracic mobility all affect form. Poor mobility can lead to:

• Rounded shoulders during pressing
  
• Wrist strain during bench or push-ups
  
• Excessive knee load during squats
  
• Back strain from stiff hips or upper spine
  

Mobility restrictions anywhere lead to compensation everywhere.

Many people have:

• Tight chest + weak upper back
  
• Tight hip flexors + weak glutes
  
• Strong quads + weak hamstrings
  
• Strong grip + weak wrist stabilizers
  

These imbalances increase risk of discomfort, instability, and poor lifting mechanics.
