We all have our preferences, but many fitness enthusiasts prefer to do cardio before strength training. While lots of people like to get their blood circulating with cardio first, others prefer to get started on the weights or machines. Does it matter? Which is best when it comes to losing fat while gaining strength? While many are still recommending that you do what feels best for you, others are touting the research on the benefits of doing weight training first. Recently, researchers explored whether weight training before hitting the treadmill is more efficient for fat reduction and improving strength. 

The research

In a study published in the Journal of Exercise Science and Fitness, researchers investigated the effects of concurrent training on fat loss, muscle strength, body composition, and physical activity levels. Concurrent training refers to workout sessions that incorporate both cardio and weightlifting exercises. The 12-week study involved 46 men who were obese and categorized into three groups:

  1. The CRE group performed resistance training before endurance training. 
  2. The CER group performed endurance training before resistance training.
  3. The control group didn’t do any exercise.

The CRE and CER groups completed three one-hour exercise sessions every week.

The results

Here are the interesting results:

  • As expected, there were no changes in the control group who didn’t do any exercise.
  • Both the CRE and CER groups experienced improvements in the following health markers: body composition, muscle strength, physical activity, VO2 max, and bone density.
  • The CRE group, which started their exercise sessions with resistance training, showed significant improvements in muscular, maximum, and explosive strength. They also saw a reduction in body fat.

It’s important to keep in mind that this is a small study that didn’t include any women.

Concluding thoughts

This study aligns with previous research, which shows that performing cardio before strength training may not be the most effective approach for maximizing strength gains and reducing body fat. If you want to maximize gains, this research also concludes that lifting weights first generates the best results. Doing cardio at the start of your workout session could also fatigue your muscles before you begin lifting.

If you really want to start out with 10 or 15 minutes on the treadmill or jogging around your neighborhood, you’ll still see benefits and improve your strength, VO2 max, and more. That being said, if you’re focused on optimizing those gains, reducing body fat, and boosting your muscular, maximum, and explosive strength, hitting those weights first might be more efficient.

Your ultimate guide to compound lifts and the powerlifting “Big Three”
Develop well-rounded strength and muscle mass with these classic compound moves.
Man performing deadlift

When you think about serious weightlifting and pumping iron, you probably envision the classic deadlift, the weighted squat, or the bench press. These exercises are the “Big Three” because they’re the foundation of powerlifting competitions used to demonstrate impressive muscular power. The “Big Three” are compound lifts that engage multiple muscle groups and joints at the same time, making them popular for those who want to optimize limited gym time. 

Many of us want to achieve certain fitness goals, such as increasing squat strength or the weight we can bench press. Compound exercises can help us develop full-body strength and muscle mass, and there are plenty of movements to choose from, including some of my favorites like the dumbbell row and the seated cable row. Read on for your ultimate guide to compound lifts, including how to do them properly, the benefits, FAQs, and safety tips.

Are you overtraining?The fitness trap that anyone can fall into
Doing too much is a common workout problem
Man running outside

If you’re athletically-oriented, your approach to fitness and workouts is structured. You have goals. Plans. A solid routine. You make room for changes and unexpected bad days, but what happens when you hit your goals and it doesn’t feel fulfilling?
This happened to me recently. I’m a lifelong runner, and my latest goal was to go from five miles a day to six, then duplicate that distance six days a week. It took weeks of hard work, but I when I finally got over the hump, I felt nothing, just a strange, unfamiliar combination of flatness and fatigue. It was a vexing problem, and it took me a while to understand that I’d succumbed to one of the most common problems in fitness — overtraining.

Depending on our busy schedules or preferences, some of us work out in the evening, such as a sunset run or a pumped-up strength training session under the amber sky. Some people seem to have difficulty sleeping often, while others drift into dreamland the second their head hits the pillow. 

There’s a lot of research to sift through regarding the best time to work out for different benefits. What about when it comes to getting restful sleep? Recently, researchers explored whether exercising within a few hours of bedtime impacts the amount of time you spend sleeping, and more. Will falling asleep be harder or easier after an evening or late-night workout? Let’s delve into the research.
