HPRC Fitness Arena: Total Force Fitness
There are many components that contribute to a Marine's optimal readiness, including physical fitness, diet and nutrition, injury prevention, and fatigue management. A balanced and effective approach for optimum performance and combat conditioning should address all four aspects. That’s where HITT comes in.
HITT is a comprehensive strength and conditioning program that takes into consideration the physical demands of operational activities to help Marines optimize their combat readiness. The HITT program focuses on the key components of superior speed, power, strength endurance, combat readiness, and injury prevention.
The four major components of the HITT program include:
- Injury Prevention (including active dynamic warm-up)
- Strength and Power
- Speed, Agility, and Endurance
- Flexibility and Core Stability
The HITT workout program can be customized as a training tool for a unit or an individual. It can also supplement your current training routine. The workouts are divided into three different modules to address each of the four components listed above.
- Athlete HITT develops basic strength and speed using barbells, kettle bells, dumbbells, speed harnesses, resistance trainers, and sleds.
- Combat HITT develops functional strength and endurance using suspension trainers, ammo cans, partner drills, and endurance training.
- Warrior HITT develops explosive power and agility using Olympic lifts, plyometrics (jumping exercises), battle ropes, cones, hurdles, and ladders.
Exercise videos provide instruction and demonstrations on how to do the exercises and movement properly. The program also uses periodization to promote long-term training improvements while avoiding over-training. Lastly, the program is categorized into specific phases, each with its own objectives and set of training parameters:
- Pre-Deployment Phase (Warrior, Combat, Athlete). The main goal is to build overall strength and performance, similar to “off-season training” in a traditional sport setting.
- Deployment Phase (Combat). The objective is to maintain overall fitness levels and reduce the risk of injuries while deployed. This is the Marine’s “in-season training”.
- Post-Deployment Phase (Athlete). The emphasis is reintegration/strengthening. If a Marine were to sustain injury or lose a significant level of performance, this phase would help get him/her return to full training status.
HITT is endorsed by the National Strength and Conditioning Associations (NSCA) Tactical Strength and Conditioning (TSAC) Department. By implementing the latest cutting-edge training methods and sound science, the HITT program builds fitness for today's tactical athlete – the United States Marine.

When you have to focus continuously for long periods of time, your brain does, in fact, become tired. Take a break: The symptoms of being mentally burned out can include irritability, lashing out at others, inability to plan, problems with decision-making, lack of drive, and performance errors. Mental fatigue can set in before you’re even aware you need a break, leading to the types of attention problems that ultimately lead to poor performance.
Mental fatigue can also include:
- Lack of clarity in your own head
- Conflict between what you’re thinking and what you are actually doing
- Feeling like you are in over your head
Mental fatigue can also make you feel tired physically, which is why it can be a greater risk for those who must sustain both focus and physical alertness. A brain busy with non-relevant matters also can be tied to feeling “spent.” You not only lose your mental edge and feel more exhausted, but you probably won’t push yourself physically as hard as you need to.
Fortunately, there are ways to combat mental fatigue. The best way is take a break and escape to a place you find relaxing or inspiring. However, if you’re in an office or on a mission, there are various mind-body strategies you can try. Mindfulness techniques are “mental push-ups” that strengthen as well as refresh your brain, so give them a try and give your brain a break.
The Marine Corps’ High Intensity Tactical Training (HITT) program is becoming more and more popular on Marine bases across the country. HITT is designed to enhance the operational fitness and optimize the combat readiness and resilience of U.S. Marines. You can now access the HITT library of exercises on the go: Download the HITT app from iTunes and Google play today!
Do you ever feel that you and your partner talk about the same issues over and over again? You’re not alone: Only 30% or so of the problems couples struggle with can actually be solved, leading to discussions that keep coming up about the other 70%. Solving the issues that can be solved is great, but learning how to interact in a positive manner about the “perpetual problems” is a good skill in any relationship.
One way to do this is to go through a structured problem-solving strategy such as this:
- Specifically state the issue.
- Briefly state why the issue is important.
- Brainstorm and discuss possible solutions to the issue.
- Have everyone involved agree on a realistic “solution”—even if it’s just a game plan for how each person is going to respond about the topic.
- Pick a specific amount of time to try the solution.
- Then give the solution a try.
Remember, the “solution” doesn’t have to mean a resolution to the problem; it can just be about new ways to approach the issue. For example, if you fight over one of you being late frequently, discuss ahead of time how you each would like the other person to respond. Maybe the latecomer needs to call or text if running late, or the punctual person calls ahead to find out if the other will be on time. And maybe you need to set a window of time rather than something exact.
November 11th is Veterans Day. HPRC would like to take this moment to thank each and every one of our Veterans and their family members who have so selflessly served our country. The VA describes Veteran’s Day as “a celebration to honor America’s veterans for their patriotism, love of country, and willingness to serve and sacrifice for the common good.”
Thank you to our Vets!
Whether you’re falling asleep or too “amped up,” you probably aren’t performing your best. Depending on who you are and what the task is, some middle ground is generally going to be best.
With simple tasks that require little conscious thinking, your reaction time is probably at its best around 60-70% of maximum heart rate (see HPRC’s article on aerobic conditioning), but response times for bigger bursts of movement improve if you’re more amped up. For example, you may be able to pull the trigger of your weapon fastest when you’re at 60-70%, but reaching for your weapon in the first place may be quickest if you’re at 90%. Keep in mind that this may not apply to more complicated tasks that involve rapid thinking, such as distinguishing a “friendly” from a “non-friendly” when someone is disguised.
There are two basic ways to get yourself amped up: physical activity and anxiety. Physical activity can happen through an intentional warm-up or even on its own because of the demands you are facing. If anything, you might find yourself needing to calm your body down. The same goes for anxiety. There’s the “butterflies-in-your-stomach” kind of anxiety and the more panicky “Darn! What do I do now?” kind. A little bit of the butterflies kind can be helpful, but again, it’s good to learn how to calm down and find middle ground!

Veterans who served in the U.S. and abroad between September 2001 and March 2010 were four times more likely than civilians to suffer from severe hearing loss. In fact, two of the most common disabilities affecting service members today are hearing loss and tinnitus, says the Hearing Center of Excellence (HCoE). Hearing loss and tinnitus seriously impact force readiness as well as the emotional and social well-being of those affected.
However, not all hearing loss results from the noise pollution Warfighters experience in the field. Many everyday exposures, such as your MP3 player or loud music in your car, can be just as damaging as firearms or helicopters. To maintain good hearing and operational readiness, Warfighters must use safe listening practices at all times. HCoE recommends these safe listening practices:
- Never listen to your MP3 player at maximum volume.
- Following the “60:60” rule: 60 percent maximum volume on your MP3 player for no more than 60 minutes a day.
- Take periodic breaks of 15–20 minutes when listening to loud music to allow your ears to recover.
- Select headphones or earbuds designed to remove background noise.
- Exercise caution when listening to music in the car. Listening in a confined space increases the risk of hearing damage.
- Wear hearing-protection devices such as earplugs at concerts, sporting events, parades, and other high-noise situations.
For more information on how to protect your hearing, as well as treatment and rehabilitation for hearing loss, please read this article from HPRC and visit HCoE.
You may not think about your feet much, but you should. The condition of your feet can make or break a ruck march, hike, or any other physical activity, especially ones that involve wearing boots. There are easy steps you can take to keep your feet blister-free, fungus-free, and in optimal shape for the many demands you put on them. Take a few minutes to self-examine your feet for any obvious problems. Military OneSource offers great advice on foot hygiene and the correct use of socks and boots. Something as simple as tying your boots correctly can prevent foot problems down the road!
Do you have a “snack drawer”? Most people do, whether it’s in their office desk, gym locker, backpack, or family minivan. Snacking can be an important part of a healthy lifestyle, preventing late-afternoon vending machine runs or mealtime overeating and providing crucial nutrients prior to workouts or missions. Snacking can also ambush otherwise healthy eating plans, so it’s important to choose snacks wisely.
Ideally, your snack drawer should be stocked with a variety of protein and carbohydrate snacks to meet your needs during the day. A healthy snack provides 100 to 300 calories, depending on your weight and activity level.
Opt for lean-protein choices such as water-packed tuna (the kind in packets fit easily into a backpack, briefcase, or purse), peanut butter, and dry-roasted nuts such as walnuts, almonds, or pistachios. If you have a fridge available, boiled eggs (up to one week) or single-serving cups of hummus, cottage cheese, or Greek-style yogurt are great choices.
Healthy-carbohydrate options include instant oatmeal or grits, whole-grain crackers, and dried fruit. Choices for the fridge include fresh fruit and veggies—a great way to get the recommended amounts you need each day.
Take advantage of snack time to add some hydration to your day. Water (flavored ones can make drinking water more appealing), milk, soymilk, and almond milk are great choices. Herbal teas provide a caffeine-free alternative. Of course, juicy fruits such as watermelon, oranges, and kiwis are terrific too.
Being prepared can help you make good choices the next time a snack attack hits. But don’t forget about food safety: Be sure to keep an eye on expiration dates and toss things when they’re past their prime. For more information about healthy snacking, read these informative tips from MedlinePlus.
