What Is Strength?


 Strength is your body’s ability to exert force against resistance. It’s the cornerstone of physical fitness, whether you're lifting groceries, running marathons, or dominating the sports field. But strength isn’t a one-size-fits-all concept—different types of strength are suited to different activities and goals.


Here are the seven types we’ll explore:

  • Agile Strength
  • Strength Endurance
  • Speed Strength
  • Explosive Strength
  • Maximal Strength
  • Relative Strength
  • Starting Strength

Understanding the different types of strength can help athletes, coaches, and trainers create more effective and targeted training programs. In this blog post, we’ll explore seven distinct types of strength, each with unique benefits and specific ways to train for them.

Strength is the ability of muscles to exert force against resistance. It’s a key component of physical fitness, essential for daily activities, sports, and exercise. For athletes, strength is crucial, regardless of the sport. Generally, there are seven types of strength: agile strength, strength endurance, speed strength, explosive strength, maximal strength, relative strength, and starting strength.

Agile strength is the ability to change direction quickly and efficiently while maintaining balance. It’s vital for athletes in sports like basketball, soccer, and tennis. The benefits include improved performance in dynamic movements, injury prevention through better balance, and versatility across sports. Training for agile strength involves agility drills like ladder runs, plyometric exercises like box jumps, and balance training using stability equipment.

Strength endurance is the ability to sustain repeated muscle contractions over time, critical for endurance athletes like runners and cyclists. Its benefits include increased stamina, faster recovery between workouts, and better overall fitness. To develop strength endurance, focus on circuit training, high-rep sets with lighter weights, and interval training that combines strength and cardiovascular exercises.

Speed strength refers to generating force quickly during high-speed movements. It’s essential for sports that require rapid, explosive actions, such as sprinting or swinging a bat. Benefits include better athletic performance, faster reflexes, and explosive power. Training includes short sprints, Olympic lifts like power cleans, and plyometric drills.

Explosive strength is the ability to produce a high amount of force in a short time, crucial for power-based sports like football and weightlifting. Benefits include increased power, improved sports performance, and activation of fast-twitch muscle fibers. To build explosive strength, incorporate Olympic lifts, high-intensity plyometrics, and resistance training with bands or chains.

Maximal strength is the maximum force a muscle group can generate in a single effort, like lifting the heaviest weight possible. This is key for powerlifters and athletes requiring peak force. Benefits include muscle growth, enhanced performance in maximum-effort activities, and stronger bones. Training involves heavy lifting with low reps and longer rest periods.


Relative strength measures strength in relation to body weight. It’s crucial for athletes in bodyweight-dependent sports like gymnastics or climbing. Benefits include better performance, reduced injury risk, and improved functional fitness. Training involves bodyweight exercises, traditional weightlifting, and maintaining a lean physique through balanced nutrition.

Starting strength is the ability to generate force at the beginning of a movement, important for sports requiring quick starts, like sprinting or Olympic lifts. Benefits include faster acceleration, better performance, and injury prevention. To train starting strength, focus on paused reps, stationary starts like deadlifts, and explosive movements like jump squats.

Proper equipment is essential for strength training. Tools like force plates, velocity-based training systems, resistance bands, and high-quality weightlifting gear can help you optimize your training program. By understanding and training for these types of strength, athletes and trainers can achieve targeted goals and elevate performance.
