Two apparently healthy young women took a cardio class from me recently. Ten minutes into the basic beginner warm-up routine, both were overwhelmed with trying to keep up. They were out of breath; their muscles were complaining; their faces were red and sweaty. They were working way too hard. I slowed the workout down, engaged them in conversation, kept the focus on simplicity of movement….and in a short while both of them regained a sense of composure and were exercising at a safer level.
Whether you’re treading water in the pool, jogging on a treadmill, cranking out miles on a cycle, smashing the racquetball or just plain lifting weights, it’s important to know if you’re working hard enough – or even too hard. A measurement called Perceived Exertion (PE) is the best way for you to judge how you’re doing and is a quicker and more individualized indicator than taking a pulse rate.
A generic pulse rate count is based on an average person of your age in an average population on an average day. If you fall outside the average measurement, you can still rely on a pulse rate to some degree to determine your workout level, but you need to stop the exercise, find your pulse on your wrist, find a clock, and start counting.... Even if you have a techno-watch-GPS-iPod-phone-heart rate monitor gizmo strapped to your arm, it still may not be accurately representing how you feel at that moment. What if you’re just coming back after the flu?
A much easier and better assessment of your activity level is Perceived Exertion. It’s based on how YOU are feeling depending on your fitness level, your goals, your workout routine, and how you feel on a given day….not on some Average Joe.
How does it work? The number scale is between 1 and 10. “1” represents the low level of energy you expend sitting in the recliner, eating popcorn and watching television. “10” – at the opposite end of the spectrum – relates to how you feel when you’re working so hard that having 9-1-1 on speed dial sounds like a reasonable option.
Here’s a brief (and lighthearted) summary of each level, from 1 to 10, for Perceived Exertion:
Level 1: I'm watching TV and eating snacks
Level 2: I'm starting to move, am comfortable, and could maintain this pace all day long
Level 3: I'm still comfortable in movement, but am breathing a bit harder
Level 4: I'm sweating a little, but feel good and can carry on a conversation effortlessly
Level 5: I'm just above comfortable, am sweating more and can still talk easily
Level 6: I can still talk, but am slightly breathless
Level 7: I can still talk, but I don't really want to. I'm sweating like a pig
Level 8: I can grunt in response to your questions and can only keep this pace up for a short time period
Level 9: I am probably going to die
Level 10: Call 9-1-1
In general, for most workouts you want to be at around Level 5-6. Think: 30 – 45 minutes on an elliptical machine or in the pool for a Hydrofit class. If you want to push yourself that day, aim for Level 7.
If you're doing interval training, you want your intensity blasts to be at around 8 and your recovery to be around a 4-5. Think: Group Power, intense cycling class, Ski Fitness.
For longer, slower workouts, keep your PE at Level 5 or lower. Think: long-distance swimming, circuit training, or 60 minutes on a treadmill.
Start paying attention to your Perceived Exertion level when you’re exercising to get a real feel for just how hard you’re truly working out. Can you still chat with someone, break a sweat and continue your workout pace? That’s the sweet spot!
