Customizing a cardio plan to work in your favor – Articles

Figuring out how much cardio you need, how hard you should be working, and which cardio exercises are best can be a real challenge when you don’t have the right tools or information. While many person are pretty clear about their exercise goals, it can be pretty easy to fall into a cardio routine that isn’t as beneficial as we may have originally hoped for. 

As part of a balanced fitness program, cardio has a lot to offer. Some of our favorite benefits include:   

Longevity (VO2 or cardiovascular capacity is one of the best predictors of long-term health and QOL)

Mood/mental health (Aerobic exercise helps stimulate “feel good” neurotransmitters and overall brain function)

Cardiovascular wellness (Exercise helps keep the heart and blood vessels healthy and resilient)

Immune health (Regular training helps stimulate and maintain healthy immune function)

Recovery (between harder training sessions, light-moderate cardio can improve blood flow and nutrient delivery to muscles that need repair)

Following the FITT Principles

As is the case with any exercise program, an effective cardiovascular training plan should utilize the FITT (Frequency, Intensity, Time and Type) principles. This is because the net effects of your chosen exercise will depend on the overall FITT of training you choose, as well as your ability to withstand and adapt to the various stressors of the training program (on top of the demands of life itself, too). 

Frequency: pertains to the number of exercise days per week. 

Frequency is contingent on several factors including the intensity of your workouts, the type of workout, as well as your exercise goals and level of fitness. Generally, 3-5 cardio sessions are recommended per week. 

Intensity: relates to how hard you work during a given workout. 

Understanding how your body responds to a variety of workout intensities is pinnacle when creating an effective cardio program. Each person burns fat and carbohydrates at varying rates, at different intensities or heart rates, which can be measured through assessments such as an Active Metabolic Assessment. You can also measure through the Silver Method, though it won’t be as accurate or detailed as an AMA. Once zones have been identified, from there we can specify an individual’s ideal heart rate training zones and customize a cardio plan that is specific to a person and their goals.  

Zone 1: Feels easy, like you could go for hours

Zone 2: Breathing is heavier, but you’re fairly comfortable

Zone 3: Breathing feels heavy, and you are working hard

Zone 4: You feel winded, and you’re pushing yourself very hard

Zone 5: You can barely catch your breath, and you’re at your absolute max


When it comes to intensity, aim for: 

  • 1-2 sessions per week that push your limits (close to an “all out” effort)
  • 1-3 sessions per week of moderate intensity
  • 1-2 sessions per week should be easy (active recovery) 

Time: accounts for the length of time of each exercise session. 

The time of your workout will be dependent on your fitness level and the type of exercise you plan to do.

When it comes to time, keep in mind: 

  • The harder the session, the shorter it should be – possibly as little as 10-15 minutes
  • Easier and moderate sessions should be 30-60 minutes keeping in mind it may be more or less based on someone’s goals

Type: is representative of the style of exercise being performed. 

There are plenty of exercise types to choose from, making this component of the FITT principles one of the easiest things you can do to change up your routine.

When it comes to type, keep in mind: 

  • Variety and enjoyment are key
  • Machines are awesome for being able to measure progress over time
  • Moving around outside or in free space are nice for mental enjoyment

Without the right type of structure or the inclusion of purposeful exercise, we can end up frustrated that our efforts aren’t yielding the results we’re expecting. If this is something you’re experiencing, it may be time to reevaluate what areas of cardio you may be getting wrong. 

4 Ways You’re Screwing Up Your Cardio

Often times when there is no plan in place or we’re training based on how we feel after a workout, it can really hold us back from seeing the results that we’re working so hard for. 

1. You’re doing cardio, but moving less the rest of your day.

Think about this for a second: you wake up early, get to the gym and you work your butt off for a solid hour, spinning your legs until they feel like mush. A puddle of sweat surrounds your bike, and your heart rate monitor says you burned a massive 950 calories during your hour in the pain cave.

nice, right? Maybe. Until later in the morning or early afternoon, when you forgo your normal walking break because you feel extra worn out today. Or later that evening, when you opt to catch a nap before dinner rather than walking the dog or mowing the lawn. It happens more than you think, but we tend to justify inactivity in the hours after a strenuous workout. And since continuous, vigorous training drains so much energy, we may turn into an inactive couch potato unless we make a conscious effort to stay active outside of the exercise sessions.

There is reason and need for lots of low-intensity movement, but most experts recommend getting the majority of that movement throughout your day instead of condensing it into one particular segment of the day.

The bottom line: have fun with your exercise sessions, but stay moving throughout the entire day too.

2. You’re doing too much.

When it comes to cardio, more isn’t always better or even necessary — especially, if you’re doing more cardio than your body is able to recover from. That said, the health benefits of cardiovascular training appear to begin after around 30 minutes of moderate intensity most days of the week (4-5 workouts totaling >150 minutes).

Doing long sessions (>60 to 90 minutes) are rarely necessary unless you’re training for a specific event that will last longer than this amount. Evidence suggests[iii] you’re better off capping your strict cardio time to about 30 minutes or so and including several days per week of resistance training for general body composition and weight improvements.

The Bottom line: more cardio isn’t better. A moderate amount of higher-quality cardio is better.

3. All your cardio sessions are the same.

In a way, cardio can be helpful for getting a little solitude, to zone out or relax; however, doing the same workout every day when you’re looking for results is definitely not going to work.

A good cardio program (or overall exercise program for that matter) incorporates a tremendous amount of variability from workout to workout. Variability of intensity, that is. Our bodies have a few major energy systems that all need to be challenged progressively over time. This leads us back to the importance of heart rate training and knowing your zones through completing an Active Metabolic Assessment. Knowing your personal heart rate zones will help you identify which types of cardio workouts you should do per week that properly force your body to develop new fitness capacity and drive results.

The Bottom line: your cardio plan should include a wide range of intensity from session to session.

4. “Cardio” has become synonymous with “I get to eat extra calories without consequence.”

Do you spend several hours each week working out so you can “allow” yourself little indulgences? Squeeze in an extra session of cardio, so you don’t feel bad eating “off plan”?

While exercising to burn off some energy may give you a little room for forgiveness — perhaps even prevent further weight gain — exercising to prepare for or undo poor eating choices isn’t guaranteed to help you see nice results. Large amounts of cardio training have been shown to induce compensatory eating patterns, especially in women [iv].

I totally get it. It’s easy to get into this mathematical mindset despite knowing that exercise is far more than just a way to expend calories. Exercise can be a potent stimulus — good or bad. Well-planned, properly executed bouts of activity can stimulate your body to go through incredible changes in fitness, health or body composition, provided you also have a stellar recuperation strategy.

The Bottom line: you can’t outrun bad food choices.

When it comes to cardio, there’s a lot to consider when coming up with a plan and strategy that is most effective for you and your goals. Instead of settling for what feels best or what seems right, make sure your cardio regimen is personalized, purposeful and gets you closer to your goals.
