Increased Injury Risk

Scientists have looked deeply at the benefits of warm-up protocols when it comes to injury risk. Injuries are a risk factor in both general fitness and athletics, so any means of reducing injury risk is highly valuable.

A recent 2022 meta-analysis of warm-up programs to prevent injuries found significant evidence that warm-ups reduced the incidents of sports injury among this population.

Earlier research has come to similar conclusions. Although some studies did not show benefits, the overwhelming majority of published studies support using warm-ups to reduce injury risk during physical activity.

With that in mind, skipping warm-ups increases your risk of injury.

Reduced Performance

Warming up isn't just about avoiding injury. In fact, warming up before your workout or activity plays a direct role in increasing your performance. Given the substantial interest in maximizing athletic performance, scientists have certainly looked into the matter.

A 2010 meta-analysis found that 79% of studies on the topic revealed that warming up led to improved performance on the various activities each study examined. More recent research has come to similar conclusions.

As such, skipping your warmup effectively reduces your performance.

Increased Soreness

Soreness after workouts is a reality of making progress in fitness. However, there is no harm in reducing soreness and the corresponding discomfort using side-effect-free methods. This includes warming up.

While you won't completely eliminate soreness with a warmup, a 2012 study found that an aerobic warm-up reduces muscle soreness in the areas of each muscle that are closer to your body.

Personally, I'll do anything I can when it comes to being less sore after workouts.

Recommended General Warm-Up Protocol

You can use the following warm-up protocol before most workouts. Do this prior to beginning the main exercises. For resistance training, you should still perform one to two lighter sets of each exercise in your program as a specific warm-up.


  1. Five minutes of light aerobic activity, aiming for a heart rate of 110 to 120 BPM.
  2. Two rounds of the following exercises:
    1. 10 small arm circles
    2. 10 large arm circles
    3. 10 Squats
    4. 10 lunges
    5. 10 downward dog to cobra flows

You can swap out other light resistance exercises, but try to focus on movements that move through large ranges of motion with your big muscles. Keep the weight very light; this warm-up should not deplete your muscles before the workout.

These 5 Grocery Items Are Cheaper Than Ever Right Now

The grocery industry has been facing major disruptions. The combined effects of the pandemic, climate change, and economic uncertainty over the past couple of years have culminated in a series of supply chain breakdowns. For the consumer, this means supply shortages , shipping delays , and temporary store closures are becoming more commonplace – and all of the added production cost to suppliers is driving up food prices . The U.S. Bureau of Labor Statistics' Consumer Price Index report for January 2022 was released on Feb. 9, and it tells the story of cost trends for every spending category over the past year. Now the numbers are in, and since January 2021, "food at home" spending has increased 7.4%. Consumers should use this number as a benchmark, Phil Lempert, the consumer behavior analyst and founder behind Supermarket Guru , told Eat This, Not That!

When Should I Take Creatine?

Creatine is probably the most well-researched supplement on the market today. Numerous studies have found positive adaptations in strength, power and muscle mass thanks to creatine supplementation—especially when it's combined with resistance training. Although the benefits of creatine are well-known to lifters, the best time to take it isn't common knowledge. Which leads us to some important questions:     Does an optimal time for consuming creatine exist?     If it does, should you take it before or after your workout? According to a new study published in the Journal of Exercise and Nutrition, the timing of creatine ingestion does indeed play a role in getting bigger and stronger. Creatine supplementation before resistance training increases muscular strength and lean muscle mass. Interestingly, taking creatine immediately after lifting weights results in greater muscle growth than taking it immediately before. However, in terms of strength gains, no difference betw
