[Energy systems] relate to how your body produces energy to fuel your workouts.

Anaerobic activities are short intervals of work used to improve speed and power, explains Lefkowith.

Think of this as a round of exercises.

Acompound exerciseis a move that incorporates multiple muscle groups, likelunges,deadlifts, andsquats.

It may also refer to two moves being strung together, like a bicep curl to a shoulder press.

This is what you do at the end of your workout.

Cross-training means mixing in different workouts and training methods rather than focusing on just one pop in of workout.

This happens because when youre working out youre damaging muscle fibers (thats a good thing!).

The muscle then repairs and rebuilds and thats how you get stronger.

This soreness may last anywhere from 24 to 72 hours after your workout.

This helps increase mobility and range of motion so you’re able to get deeper into exercises.

This is crucial for performing exercises with correct form and making sure the right muscle fibers are firing away.

This generally refers to exercises that help you move and feel better in every day life, says Lefkowith.

According to theAmerican Heart Association, the average is 60-100 BPM.

You also have your maximum heart rate, which is the hardest your heart can work efficiently.

HIIT stands forhigh-intensity interval training.

This refers to tough quick, intense bursts of exercise, followed by short recovery periods.

An interval is simply a period of activity or a period of rest.

Think wall sits and planks.

They are a great way to build stability and strength.

Examples would include squat jumps, box jumps, broad jumps, andburpees.

One of the main purposes of these explosive exercises is increasing power, says Laferrera.

Plus, because these moves get your heart rate up, theyre big calorie-burners.

Saying 12 reps means doing an exercise 12 times.

Resistance means how much weight your muscles are working against to complete a movement.

That can mean anywhere from your own bodyweight to a set of five-pound dumbbells to a 50-pound kettlebell.

This stands for rate of perceived exertion, and refers to intensity.

This jot down of endurance training is especially beneficial if youre training for a race or event.

The goal of this punch in of workout is to increase muscle mass.

Super setting means pairing two exercises and doing them back-to-back, explains Lefkowith.

Or, you could do two exercises that work the same area to completely fatigue one muscle group.

Another option is to pair push and pull movementsfor example, a push-up and a pull-up.

And because youre doing movements paired together, youre likely to raise your heart rate, too.
