How many 'Sets' and 'Reps' in Strength Training?
The terminology in exercise routines can sometimes seem confusing. If you've looked into training programs, you've probably encountered the terms 'sets' and 'reps.' If these concepts are unclear, don’t worry. We’re here to clarify.
What Are ‘Sets’ and ‘Reps’?
A ‘rep,’ short for repetition, refers to the number of times you perform an exercise before taking a break. A ‘set’ is a group of these repetitions. For instance, if you do 4 sets of 5 reps of bench press, you perform the movement 5 times, rest, and then repeat for a total of 4 sets.
Determining the Number of Reps in a Set
The number of reps in a set depends on your fitness goals. Generally, there are three rep ranges based on different objectives:
Strength Focus: Lower reps with heavier resistance, typically 1-8 reps per set for 3-10 sets.
Hypertrophy (Muscle Growth): Higher reps, usually 3-6 sets of 7-12 reps. Various approaches can be effective, such as 8 sets of 3 reps with less rest time.
Muscular Endurance: Very high reps, generally in the range of 15-30+ reps per set.
Mechanisms of Muscle Growth
When aiming for hypertrophy, it's important to understand the three mechanisms that drive muscle growth:
Mechanical Tension: Using heavy loads and performing exercises through the full range of motion (ROM). This is often referred to as 'time under tension.'
Muscle Damage: Microtears in the muscle fibers occur during resistance training. These are repaired during recovery, leading to muscle growth. This process triggers mTor pathways, activating protein synthesis to rebuild the muscle.
Metabolic Stress: Created by lifting moderate to light weights for higher repetitions, causing a blood pooling effect within the muscle. This restricted blood flow and lack of oxygen lead to a buildup of metabolites like lactate, which promotes an anabolic effect and muscle growth.
Effective Combinations of Reps and Sets for Strength
Beginners can gain significant strength and muscle mass with moderate sets and reps, incorporating progressive overload. Here are some broad guidelines:
Maximal Strength: 3-5 sets of 1-3 reps at 80% of your rep max.
Explosive Strength: 6-10 sets of 1-3 reps at 60-70% of your rep max, performed as quickly as possible while maintaining good form.
Strength and Hypertrophy Combination: 4-8 sets of 4-8 reps at 70-80% of your rep max.
Strength vs. Cardio: Sets and Reps
Strength training focuses on overcoming external load and stimulating mechanical tension with heavy resistance. Cardiovascular training aims to increase heart rate and work the cardiovascular system through prolonged activity.
In strength-focused workouts, you'll perform low reps with heavy weights and take longer rests. In contrast, cardio workouts are measured by time, distance, or heart rate, aiming to keep you active and increase heart rate. Some strength exercises might get you out of breath, but the main goal remains mechanical tension and muscle growth.
