What are the quadriceps?
This is the total number of rep groupings you perform for an exercise
What is a set?
This is exercise that is performed for a longer duration of time at a consistent speed
Steady State Cardio
This essential recovery activity helps your muscles rebuild and your brain recharge. Most adults need 7–9 hours of it per night
What is sleep?
These are the three types of macronutrients your body needs in large amounts for energy and recovery
What are protein, carbohydrates, and fat?
This muscle makes up 2/3 of the total mass of the arms
What are the triceps?
This type of muscle contraction happens when your muscle shortens under tension, like lifting a dumbbell
What is a concentric contraction?
According to health guidelines, adults should aim for at least this many minutes of moderate-intensity aerobic exercise per week to support overall health
What is 150 minutes?
Taking at least one of these per week gives your body time to rest, repair, and rebuild
What is a rest day?
There are 9 calories in each gram of this macronutrient, making it the most calorie-dense of the three
What is fat?
These types of muscle fibers are able to use high amounts of oxygen
What are type 1 muscle fibers?
When training to gain strength, you should gradually increase the weight or difficulty over time. This principle is called:
What is progressive overload?
As your cardiovascular fitness improves, your resting heart rate usually does this
What is decrease?
After a tough workout, you might feel sore for 1–3 days. This common condition has a four-letter acronym and happens as your muscles recover
What is DOMS (Delayed Onset Muscle Soreness)?
This type of carbohydrate, found in oats, fruits, and vegetables, supports digestion and helps keep you full
What is fiber?
This is the largest muscle group in the human body
What is the gluteus maximus?
This training method alternates between two exercises that target different muscle groups with little to no rest
What is a superset?
This is the name for the highest amount of oxygen your body can use during intense exercise, and it’s a common measure of cardiovascular fitness
What is VO₂ max?
Training too hard and too often without enough rest can lead to this condition, which can hurt your progress and increase injury risk
What is overtraining?
This term refers to how much energy your body uses at rest to maintain basic functions like breathing and digestion
What is basal metabolic rate (BMR)?
This is used by the body to produce energy
What is ATP?
This ability to move quickly and forcefully becomes more important as we age because it helps us stay independent, avoid falls, and react to everyday challenges
What is power?
As your heart becomes more efficient through regular cardio exercise, this measure increases, meaning your heart doesn't have to beat as often to deliver the same amount of blood
What is stroke volume?
This theory describes how the body reacts to different levels of physical stress over time, including phases of shock, adjustment, and potential burnout
What is General Adaptation Syndrome?
This amino acid helps to stimulate protein synthesis
What is Leucine?
