Morning Workouts: Fat Burn, Focus & Habit Stacking

Why are morning workouts effective?

Hormones working for you: Cortisol and testosterone are typically highest very early in the morning. Cortisol helps with releasing stored energy, while testosterone repairs and builds muscle - this is especially important with resistance training.

You don't want to eat before workouts: Working out before eating may enhance fat oxidation by as much as 20%! This is helpful for anyone working towards either fat loss or metabolic flexibility.

Mood & focus: Morning exercise increases dopamine, serotonin and norepinephrine in the brain for focused attention and improved mood - so you aren't just exercising to burn calories, but also supporting your brain for the challenges of the day ahead!

Sleep and training: Studies suggest an early workout better improves sleep quality and sleep quantity when compared to evening workouts. Early workouts also better support your circadian rhythm than evening workouts, and therefore help you fall asleep easily and stay asleep.

Best for:
· Fat Loss
· Habit Formation
· Optional mental clarity
· For the early bird, structured person.

Watch out for: Increased risk of injury due to a colder body, increased joint stiffness and smaller range of motion - You may require longer warm-up times and more mobility prep.

Pro tip: If you train fasted, consider BCAAs or electrolyte salts to help you perform better without breaking your fast.

Mid-Afternoon Training: Strength, Power & Performance Peaks

Reasons why it works:

• Circadian rhythm timing – Physical function plateaus from 2–6 p.m. Your body temperature, reaction time, and muscle pliability will be at their best during this time, which enhances strength output, coordination and decreases the chance of injury.

• Strength increases – Research has shown that men can have better management of blood pressure and strength performance during the afternoon compared to other time frames. The afternoon window is the best time for personal records and progressive overload.

• Fuel benefits – You have had three square meals, fluid, and all the micronutrients your body and muscles need from breakfast to lunch. Your glycogen stores are a pretty good place to be for the demands of training, ensuring you can endure longer and have better recovery from the training session.

Best for:
• Strength training
• High-intensity interval training (HIIT)
• Athletes and performance seekers

What to watch out for: • Energy dips (mid-day) caused by a non-optimized nutrition, or hydration regime • Setting yourself up for success when scheduling training may conflict with work or family priorities

Pro tip - To improve your overall work output, have a light snack before training (around 60–90 min). Anything like a banana + nut butter will do. If you do the right top up before training, you won't feel sluggish.

Evening Sessions: Gains, Stress Relief & Sleep Trade-offs

Why they work:

• Stress relief: Evening workouts can reduce cortisol and help you decompress after a long day. An effective emotional regulation and mental reset tool.
• Muscle recovery: Some studies show that evening resistance training may enhance hypertrophy through higher body temperature and neuromuscular efficiency.
• Flexibility: Perfect for people with hectic mornings or uncertain schedules. When training is the last thing you do, you are much less likely to miss the opportunity for a workout.

Best For:
• Building muscle
• Stress relief
• Not-so-Early Birds: Night owls and shift workers

What to watch for: • You may encounter sleep issues if training too close to your bedtime. Elevated heart rates and body temperature can delay falling asleep and/or reduce deep sleep quality • You may be prone to late-night hunger spikes after training - make sure you plan your meals to avoid late-night binge eating.

Pro tip: Try to wrap up your training at least 90 minutes before bed. You can eat a meal high in magnesium (salmon + greens) right after training to enhance recovery, and it may even help with sleep.
