Strength training, also known as resistance training, is a form of physical exercise that focuses on building and developing muscular strength, endurance, and power.

It involves using external resistance, such as free weights, weight machines, resistance bands, or body weight, to create resistance against your muscles.

The primary goal of resistance training is to progressively overload the muscles, forcing them to adapt and become stronger over time.

You can achieve that by performing exercises that target specific muscles or multiple muscle groups simultaneously.

Benefits of Strength Training

Strength training offers several benefits, including:

  • Increasing muscle strength and mass
    Regular strength training leads to muscle hypertrophy or growth. It can also help boost your strength, allowing you to perform daily activities much better and more efficiently.
  • Enhancing Bone Health
    Resistance training puts stress on the bones. That can stimulate the process of bone remodeling and help prevent age-related bone loss.
  • Improved body composition
    Strength training can help reduce body fat percentage, increase lean muscle mass, and help build a more toned and better-defined physique.
  • Speeding up metabolism
    Muscle can burn more calories at rest than fat. Building muscle through resistance training can boost your metabolism, making it easier to maintain a healthy weight or lose body fat.
  • Helping to prevent injury
    Strengthening muscles, tendons, and ligaments through resistance training can improve joint stability and reduce the risk of injury during physical activities or sports.
  • Enhancing functional capacity
    Strength training can help improve physical performance, making it much easier to carry out everyday tasks and activities, such as lifting heavy objects or climbing stairs.
  • Better Posture and Alignment
    Strength training exercises that target postural muscles can improve posture and alignment.
    That can help reduce the risk of musculoskeletal imbalances and associated pain or discomfort.
  • Boosting Physical Function and Performance
    Resistance training can increase physical performance and functional capacity.
    That can translate to increased athletic performance, higher efficiency in daily activities, and a reduced risk of age-related declines in physical function.
  • Positive Impact on Mental Health
    Studies show that resistance training can benefit mental health (1, 2, 3). It can reduce symptoms of depression, anxiety, and stress, improve cognitive function, boost self-esteem and body image, and enhance overall mood and well-being (4).
  • Chronic Disease Management
    Studies show strength training can help prevent and manage several chronic conditions, including cardiovascular diseases, type 2 diabetes, arthritis, and osteoporosis (5).

Types of strength training equipment

You can do strength training using various types of equipment.

Your personal preferences, access to facilities, and specific goals will influence your choice of equipment.

Some common types of equipment used in resistance training include,

Body weight

using body weight for strength training

Exercises that rely on your body weight, aka bodyweight exercises, require no additional equipment and utilize the weight of your body for resistance.

Examples of exercises that use your body weight include push-ups, pull-ups, air squats, lunges, planks, and burpees.

Bodyweight exercises are versatile. You can modify them to suit different users and fitness levels.

Free Weights

Free weights include dumbbells, barbells, and weight plates.

They offer several exercise options and allow for greater freedom of movement.

Dumbbells are versatile. You can use them for several exercises, including bicep curls, shoulder presses, and lunges.

Barbells consist of a long metal bar with weight plates attached to each end.

You can use barbells for several exercises, including squats, bench presses, and deadlifts.

Weight machines provide a guided range of motion and target specific muscle groups.

They are suitable for beginners or athletes looking to isolate particular muscles.

Examples of weight machines include leg presses, chest presses, lat pulldowns, and leg extensions.

Resistance Bands

Resistance bands are elastic bands that provide resistance when stretched.

They are portable and affordable. You can use various exercises to target different muscles.

Resistance bands are available at various resistance levels, making them suitable for exercisers of different fitness levels.


Kettlebells are cast-iron weights with a handle.

You can use kettlebells for dynamic movements to target and engage multiple muscles, promoting strength, endurance, and mobility.

Kettlebell exercises include swings, Turkish get-ups, snatches, and goblet squats.

Medicine Balls

Medicine balls are weighted balls available in various sizes and weights.

You can use medicine balls for resistance exercises, core strengthening, and explosive movements.

Medicine ball exercises include wall balls, Russian twists, overhead slams, and medicine ball push-ups.

Suspension Training Systems

Suspension training systems, such as TRX, utilize straps and handles suspended from an anchor point.

You can use them to add more resistance and challenge to bodyweight exercises to target multiple muscles while challenging stability and core strength.

Basic Principles of strength training

Strength training adheres to several basic principles that help guide the design and effectiveness of a training program. These principles include:

Progressive Overload

The principle involves gradually increasing the demands placed on the muscles over time.

It means continually challenging the muscles by increasing resistance, volume – sets and repetitions – or intensity to stimulate further strength gains.

Progressive overload is essential for continued adaptation and improvement.


The principle of specificity states that the training program should be specific to the desired goals.

Different exercises and training methods target various muscles and movement patterns.

If your goal, for example, is to improve squat strength, incorporating squats into your training regimen is more specific than focusing on exercises unrelated to squatting.

What works for one person may not work for another.

Thus it is better to tailor your strength training programs to your needs, goals, fitness level, and capabilities.

Personalization allows for optimal progression, addresses weaknesses or imbalances, and considers factors like age, injury history, and training experience.


Variation refers to regularly changing parts of your training program, such as exercise selection, intensity, volume, or rest periods.

Variation can help prevent plateaus, boredom, and overuse injuries.

It will allow you to introduce new stimuli, letting you challenge the body continuously and forcing it to adapt.

Recovery and Rest

Adequate rest and recovery are crucial for optimal strength gains.

Strength training can lead to injury, resulting from continuous stress on muscle tissues, and recovery allows for repair and growth.

Overtraining or insufficient rest can hinder progress and increase the risk of injury. Building rest days and recovery periods into your training program is essential.

Proper Technique

Performing exercises with proper form and technique is essential for safety and effectiveness.

It ensures the targeted muscles are engaged correctly, minimizes the risk of injury, and maximizes the benefits of each exercise.

We recommend you take steps to learn the correct technique from a qualified professional, especially for complex or heavy lifts, if necessary.


A periodization is a planned approach to organizing training into specific periods or cycles.

It involves manipulating variables, such as intensity, volume, and exercise selection over time to optimize progress.

Periodization includes phases of higher volume or intensity followed by periods of lower magnitude for recovery or adaptation.

Applying the above principles can help exercisers design effective strength training programs that can lead to improved strength, muscle growth, and
overall fitness.

It is worth noting that the principles are not rigid rules but guidelines that can be adapted based on

Strength training limitations

Strength training has numerous benefits, but it has some limitations worth noting.

  • Risk of Injury
    Like any exercise, resistance training can cause injury if performed incorrectly or with poor form.
    It is essential to learn proper techniques, start with appropriate weights, and gradually progress to avoid strain, sprains, or other injuries. Consult a qualified fitness professional, where necessary, to help ensure your safety and help you train effectively.
  • Specificity of Goals
    Strength training focuses on improving muscular strength, endurance, and power. While it can help improve your fitness, it may not directly address other issues, such as cardiovascular endurance, flexibility, or coordination.
    You may have to combine resistance training with other forms of exercise to help achieve a well-rounded fitness program.
  • Time Commitment
    Strength training requires regular and consistent training sessions to help get significant results.
    Finding time for dedicated resistance training workouts may be challenging for some exercisers.
    Note, however, that even shorter, focused sessions can provide benefits when done effectively.
  • Individual Differences
    What works for one exerciser may not work for another.
    Thus, strength training programs should be individualized to account for differences in fitness levels, age, health conditions, and specific goals.
    Adapt programs to individual needs and seek guidance from professionals if necessary.
  • Equipment and Access
    Some strength training exercises may require access to specific equipment or facilities, such as weights, machines, or a gym.
    Exercisers with limited access to the equipment may have fewer exercise options.
  • Muscular Imbalances
    Strength training can lead to muscular imbalances if not planned with care.
    Neglecting some muscle groups can create postural or functional issues.
  • Health Considerations
    Certain health conditions or injuries may require modifications or specific precautions during resistance training.
    It will be necessary to consult a healthcare professional or qualified fitness expert in such situations.
  • Hitting Plateaus
    Your body adapts to a training stimulus after a while, making it challenging to get more results from your training.
    Applying the principles of progressive overload, varying the training routine, and periodically reassessing and adjusting your training program can help if you hit a plateau.

Despite the limitations, resistance training is a valuable exercise for most people.
You can mitigate the risks and maximize the benefits of strength training by understanding and addressing the limitations.

Final words from LiveLIfe

Strength training is an excellent way to burn calories, build muscle mass, and speed up the metabolism.

Adopting resistance training as part of your training regimen can offer several health benefits and help improve your quality of life.

While some equipment can enhance strength training, it’s not always necessary.

You can do strength training exercises with just your body weight or minimal equipment.

Thus having no equipment, or access to any, should not be a barrier to incorporating resistance training into your fitness regimen.

It is essential to follow proper form and technique to ensure safety and maximize the effectiveness of the exercises when engaging in strength training.

Beginners should always start with lighter weights and gradually increase the resistance as they become more comfortable and stronger.

Remember to allow enough rest and recovery between workouts. That will give the muscles time to repair and grow.

Consult a qualified fitness professional to help design a strength training program tailored to your goals and abilities.
