Plyometrics: Three explosive exercises even beginners can try

As a kid, I spent many Saturdays romping around my Florida neighborhood imitating Colonel Steve Austin, better known as The Six Million Dollar Man to avid TV watchers in the 1970s.

The popular show featured a bionic man — half human and half machine — who could jump from three-story buildings, leap over six-foot-high walls, and bolt into a full 60-mile-per-hour sprint. Naturally, these actions occurred in slow motion with an iconic vibrating electronic sound effect.

My own bionic moves involved jumping to pluck oranges from tree branches, hopping over anthills, and leaping across narrow ditches while humming that distinctive sound. I didn’t realize it, but this imitation game taught me the foundations of plyometrics — the popular training routine now used by top athletes to boost strength, power, and agility.

What are plyometrics?

Plyometric training involves short, intense bursts of activity that target fast-twitch muscle fibers in the lower body. These fibers help generate explosive power that increases speed and jumping height.

“Plyometrics are used by competitive athletes who rely on quick, powerful movements, like those in basketball, volleyball, baseball, tennis, and track and field,” says Thomas Newman, lead performance specialist with Harvard-affiliated Mass General Brigham Center for Sports Performance and Research. Plyometrics also can help improve coordination, agility, and flexibility, and offer an excellent heart-pumping workout.

Who can safely try plyometrics?

There are many kinds of plyometric exercises. Most people are familiar with gym plyometrics where people jump onto the top of boxes or over hurdles.

But these are advanced moves and should only be attempted with the assistance of a trainer once you have developed some skills and muscle strength.

Keep in mind that even the beginner plyometrics described in this post can be challenging. If you have had any joint issues, especially in your knees, back, or hips, or any trouble with balance, check with your doctor before doing any plyometric training.

How to maximize effort while minimizing risk of injury

  • Choose a surface with some give. A thick, firm mat (not a thin yoga mat); well-padded, carpeted wood floor; or grass or dirt outside are good choices that absorb some of the impact as you land. Do not jump on tile, concrete, or asphalt surfaces.
  • Aim for just a few inches off the floor to start. The higher you jump, the greater your impact on landing.
  • Bend your legs when you land. Don’t lock your knees.
  • Land softly, and avoid landing only on your heels or the balls of your feet.

Three simple plyometric exercises

Here are three beginner-level exercises to jump-start your plyometric training. (Humming the bionic man sound is optional.)

Side jumps

Stand tall with your feet together. Shift your weight onto your right foot and leap as far as possible to your left, landing with your left foot followed by your right one. Repeat, hopping to your right. That’s one rep.

  • You can hold your arms in front of you or let them swing naturally.
  • Try not to hunch or round your shoulders forward as you jump.
  • To make this exercise easier, hop a shorter distance to the side and stay closer to the floor.

Do five to 15 reps to complete one set. Do one to three sets, resting between each set.

Jump rope

Jumping rope is an effective plyometric exercise because it emphasizes short, quick ground contact time. It also measures coordination and repeated jump height as you clear the rope.

  • Begin with two minutes of jumping rope, then increase the time or add extra sets.
  • Break it up into 10- to 30-second segments if two minutes is too difficult.
  • If your feet get tangled, pause until you regain your balance and then continue.

An easier option is to go through the motions of jumping rope but without the rope.

Forward hops

Stand tall with your feet together. Bend your knees and jump forward one to two feet. Turn your body around and jump back to the starting position to complete one rep.

  • Let your arms swing naturally during the hop.
  • To make this exercise easier, hop a shorter distance and stay closer to the floor.
  • If you want more of a challenge, hop farther and higher. As this becomes easier to do, try hopping over small hurdles. Begin with something like a stick and then increase the height, such as with books of various thicknesses.

Do five to 10 hops to complete one set. Do one to three sets, resting between each set.

Orienteering: Great exercise and better thinking skills?

Picture this: you’re with friends in an unfamiliar forest using only a map and a compass to guide you to an upcoming checkpoint. There are no cell phones or GPS gadgets to help, just good old brainpower fueled by a sense of adventure as you wind through leafy trees and dappled sunlight.

This is not an excursion to a campsite or a treasure hunt. It’s a navigation sport called orienteering — a fun way to get outside, exercise, and maybe even help fight cognitive decline, according to a 2023 study.

What is orienteering?

Orienteering combines map and compass reading with exercise. Competitors (“orienteers”) race against a clock to reach checkpoints in outdoor settings that can range from city parks to remote areas with mountains, lakes, rivers, or snowy fields.

“You can go out in a group or on your own. You get a very detailed map and navigate your way to checkpoints that record your time electronically,” says Clinton Morse, national communications manager with Orienteering USA, the national governing body for the sport in the United States.

Because orienteers are racing the clock, they might run on trails, hike up hills, or scramble around boulders. That’s for foot-orienteering events. There are also orienteering events with courses geared for mountain biking, cross-country skiing, or canoeing.

How might orienteering affect thinking skills?

A small 2023 study published online in PLoS One found a potential link between orienteering and sharp thinking skills.

Researchers asked 158 healthy people, ages 18 to 87, about their health, activities, navigation abilities, and memory. About half of the participants had varying levels of orienteering experience. The other participants were physically active but weren’t orienteers.

Compared with study participants who didn’t engage in orienteering, those who were orienteers reported

  • having better navigational processing skills (recognizing where objects were, and where participants were in relation to the objects)
  • having better navigational memory skills (recalling routes and landmarks).

The study was observational — that is, not a true experiment — and thus didn’t prove that orienteering boosted people’s thinking skills. But the link might be plausible.

“Aerobic exercise releases chemicals in the brain that foster the growth of new brain cells. And when you use a map and connect it to landmarks, you stimulate growth between brain cells,” says Dr. Andrew Budson, lecturer in neurology at Harvard Medical School and chief of cognitive and behavioral neurology at VA Boston Healthcare System.

Where can you find orienteering opportunities?

There are about 70 orienteering clubs across the United States, and many more around the world (the sport is extremely popular in Europe). To find an orienteering event in your area, use the club finder tool offered by Orienteering USA.

How can you get started with orienteering?

People of all ages and athletic levels can take part, because orienteering courses vary from local parks to wilderness experiences. Costs are about $7 to $10 per person for local events, or $25 to $40 per person for national events, plus any travel and lodging expenses.

To make orienteering easy at first, Morse suggests going with a group and taking things slowly on a short novice course. “You don’t have to race,” he says. “Some people do this recreationally to enjoy the challenge of completing a course at their own pace.”

The trickiest part is learning to read the map. Morse’s advice:

  • Turn the map as you change directions. Hold the map so that the direction you’re heading in is at the top of the page. For example, if the compass indicates that you’re heading south, turn the map upside down, so the south part is on top and easier to follow.
  • Create a mental image of what the map is telling you. If there’s a fence along a field on the map, build a picture of it in your mind so you can recognize it when you see it, even if you haven’t been there before.

Tips for safe and enjoyable orienteering events:

  • Dress appropriately. Wear comfortable clothes including long pants, good walking shoes, and a hat.
  • Lather up. You’ll be outside for at least an hour, and you’ll need sunblock and possibly tick and bug spray depending on the terrain. Preventing tick bites that can lead to Lyme disease and other tick-borne illnesses is important in many locations.
  • Bring some essentials. Pack water, a snack, sunblock, bug spray, and your phone. (Keep the phone turned off unless you need to call for help.)
  • Use good judgment. Know that the shortest route on the map won’t always be the best, since it might take you up a hill or through thick vegetation. It might be better to go around those areas.

Once you learn the basics of orienteering, you can make it more physically challenging (and a better workout) by going faster and trying to beat your previous times, or by signing up for a more advanced course that’s longer and requires more exertion and speed.

And no matter which event you take part in, enjoy the adventure. “You’re not just following a path, you’re solving puzzles while being immersed in nature,” Morse says. “It’s a great way to experience the outdoors.”
