Interval training, sometimes referred to as high-intensity interval training (HIIT), has become an incredibly popular form of exercise in recent years due to its ability to torch calories and body fat in a short amount of time. However, interval training offers specific benefits for men looking to naturally boost testosterone levels and build strength and muscle mass. Let’s explore why interval training is so effective and how men can utilize it in their workouts.
Story Stages
The Science Behind Interval Training
Interval training is bursts of high-intensity exercise with periods of rest or lower intensity in between reps. For example, a HIIT workout might consist of a warmup followed by six to eight repetitions of a sprint or full-out effort for 30 seconds, followed by 60 to 90 seconds of recovery.
Research has found that this type of training triggers the release of key hormones, like human growth hormone and testosterone, at a greater level than steady-state cardio. The intensity signals your body to adapt by getting fitter and stronger, which requires elevating anabolic hormones. One major study found that just two weeks of HIIT boosted testosterone levels in young men by almost 15 percent. The metabolic disruption caused by the intensity is also believed to turbocharge fat burning. Using an estrogen blocker for men can also increase testosterone levels and enhance the benefits of HIIT workouts.
Programming an Effective Interval Training Session
When designing an interval training program, it’s important to incorporate a variety of exercises to target different muscle groups and energy systems for maximum benefits:
- Sprints: Explosive sprints, like hill sprints or flat ground sprints, are incredibly effective for spiking testosterone and human growth hormone while torching body fat. Aim for a work-to-rest ratio between 1:5 to 1:10 when sprinting. Uphill and downhill sprints challenge different muscles and energy systems.
- Kettlebell Training: Exercises like kettlebell swings performed in interval fashion can help build strength and power while improving conditioning. Time your sets based on repetition goals rather than seconds when lifting. Single-arm and double-arm work provides variation to target imbalances.
- Rowing: Whether on a rowing machine or actual rowing on water, working the intervals helps build full-body power and endurance. Mix up intervals between time and distance pieces for diversity. Focus on engaging the legs before arms and back for maximal power.
- Bodyweight Training: Burpees, jumping lunges, and pull-ups done at high-intensity quickly fatigue the muscles and reset anabolic hormones. Modify exercises as needed by reducing impact or using assistance. Complete complementary core training like planks and side planks to build a strong foundation.
Nutrition Support for Interval Training
To support intense interval training, men need to pay special attention to nutrition:
- Carbs: Interval training requires fast energy from glycogen stores, so make sure you adequately fuel up on healthy complex carbs from sources like quinoa, sweet potatoes, and fruits. Time carb intake appropriately by consuming most carbs in the post-workout window and around workouts. Starchy vegetables and ancient grains provide sustained energy between high-intensity intervals.
- Protein: Whey protein after a workout helps kickstart the recovery and rebuilding process to support muscle and strength gains. Shoot for 20 to 40 grams. Casein protein before bed provides amino acids to muscles overnight. Increase daily protein intake to around 0.7-1 gram per pound of body weight when training intensely.
- Micronutrients: Don’t neglect vitamin C, magnesium, and zinc as key players in testosterone production and immune function. Vitamin D also directly correlates with testosterone levels, so supplement accordingly. Suboptimal nutrient levels hamper performance, recovery, hormones, and muscle building.
By combining strategic high-intensity intervals with proper nutrition support, men can maximize the effectiveness of their training for enhancing fitness, building strength, supporting testosterone, and accelerating fat loss. Just be sure to start gradually and allow for proper rest between interval sessions.
