HIIT vs. Weight Training: Are You Using the Right Workout for Your Goals?
Stop spinning your wheels—discover the key to aligning your workouts with what you actually want to achieve.
How to stop guessing and start training with purpose
Many view High-Intensity Interval Training (HIIT) as a magic bullet, a quick, low-effort fix to achieve every fitness goal, from ripped physique to endless stamina. While HIIT’s time efficiency is appealing, fitness success demands more than shortcuts. HIIT and weight training each offer powerful benefits, like improved endurance or increased strength, but their effectiveness depends on your objectives. I hope to explain in a bit more detail how to ensure that your training is aligning with your fitness goals. Ensuring more clarity and confidence in your actions.
HIIT: Is it Cardio Training or Muscle Growth?
HIIT has gained significant popularity for its efficiency and intensity. It involves brief bursts of vigorous exercise followed by short rest periods. HIIT is highly effective for improving cardiovascular endurance, supporting explosive sports like hockey, or fitting a productive workout into a busy schedule. This is where people tend to go wrong, as many people are using HIIT to train for goals that HIIT isn’t best served for. When we are looking at the goals that align better with HIIT:
Intense Cardio Goals
Training for specific activities that need explosive output (Think hockey shifts)
Looking to create time efficient exercise not focused on optimization
However, HIIT isn’t a one-size-fits-all solution. Many believe it builds muscle as effectively as weight training, but its high cardio demands often limit muscle growth, especially for those with stronger muscles but weaker endurance. This mismatch can lead to frustration if your goal is to build muscle rather than improved stamina. It’s not that HIIT is “bad,” but the mindset that follows can be problematic. If you believe you're building muscle but are actually limited by your cardio capacity, you may get discouraged when results don’t match your expectations.
HIIT can benefit most individuals, depending on their objectives. For those with strong cardiovascular fitness, exercises like sprinting may contribute to muscle development, though less effectively than weight training. The challenge lies in pushing muscles to near failure, which is difficult in cardio-intensive workouts. Athletes, such as hockey players, often use HIIT for efficient conditioning directly useful for their sport. While also getting some muscle growth qualities as they’re able to push their muscle to be the limiting factor.
HIIT may not be the best savior around but it can still provide the basis for muscle growth and progress. For those looking to grow muscle or lose weight they may still want to explore a more traditional style of weight lifting. Focused on optimizing for muscle growth and keeping their cardio on separate times or separate days all together.
Weight Training: Building Muscle with Focus
Traditional weight training focuses on building muscle and strength by targeting specific muscles through controlled movements. Unlike HIIT, it ensures your muscles, not your cardio capacity, are the limiting factor, maximizing growth and strength gains. You can choose from styles like powerlifting (heavy compound lifts like squats and deadlifts), bodybuilding (emphasizing muscle isolation), machine-based workouts (offering controlled movements for beginners), or even unique equipment like kettlebells or sandbags.
All of these are examples of training styles that would fall under traditional weight lifting ideas. These all use weights in order for us to progressively add a bit more each week all while ensuring the muscle strength and endurance is the limiting factor. Whether you enjoy lifting heavy, doing high reps, or switching up your equipment, weight training lets you focus your efforts far more directly than a HIIT workout does.
The big draw of HIIT over a more traditional style of lifting is the time efficiency, however, there are also many ways of us turning more traditional styles of lifting into more time efficient alternatives. Try techniques like:
Supersets: Alternate two exercises (like push-ups and rows) with rest only after both.
Giant Sets: Cycle through three or more exercises, similar to a circuit but resting until you’re ready.
Drop Sets: Perform one exercise for multiple sets with minimal rest, lowering weight to hit more reps near failure.
Myorep Sets: Take one exercise to failure multiple times with 3-4 breaths between attempts.
Each style employs progressive overload, gradually increasing resistance to build muscle strength and endurance. Whether you prefer heavy weights, higher repetitions, or varied equipment, weight training offers focused, goal-oriented efforts compared to HIIT’s more cardio focused approach.
Choosing the Right Tool for Your Goal
The distinctions between HIIT and weight training should now be evident. Each offers unique benefits, but selecting the appropriate method for your goals is essential to ensure effective progress. Few things are more discouraging than realizing your efforts do not align with your intended outcomes.
HIIT is your go-to for cardio gains and time efficiency. It’s perfect for sports requiring short, intense bursts, like sprinting down a soccer field, or everyday challenges like keeping up with energetic kids. If you need to last longer during high-effort tasks, HIIT can train your body to recover faster and push harder. Making sure you have that purpose is going to be very important!
Weight training shines for muscle growth, strength, and body composition changes. It lets you isolate muscles, push them to failure, and adapt specifically for strength, endurance, or size. If you’re hoping to expand your metabolism or change your body composition then this is the area that you’re going to want to look for. If you find yourself being a bit weak in day to day activities, then focusing your training toward gaining strength will make the biggest difference in your life, which weight training does allow you to do.
That said, not every choice is about optimization. Maybe you just love the sweaty, high-energy feel of a HIIT session. If it brings you to exercise and keeps you doing it, then absolutely do not let this stop you. My goal is to outline the trend that is happening and have you critically assess whether it is truly the right decision for you and the goals that you’re seeking to achieve. Do what you enjoy and what you will consistently commit to!
Aligning Your Training for Lasting Success
HIIT and weight training each hold unique strengths, HIIT excels for cardiovascular fitness and time efficiency, while weight training drives muscle growth and strength. Both are valid ways of training but jumping on a trend rather than ensuring your workouts match your goals. Rather than chasing quick solutions, choose intentionally what is important for you and tailor your training toward matching those goals. That is going to help not only make the most progress toward your goal possible but ensure you’re not going to be frustrated when your outcomes don’t align with your expectations!
