Three Effective Recovery Tricks Post-workout

1. Prioritize protein within 30-60 minutes post-workout: Your muscles need amino acids to repair and rebuild, so aim for 20-30 grams of quality protein like Greek yogurt, a protein shake, eggs, or lean meat. This helps kickstart muscle protein synthesis when your body is most receptive to nutrients.

2. Use active recovery instead of complete rest: Light movement like a 10-15 minute walk, gentle stretching, or easy yoga helps increase blood flow to your muscles, which delivers nutrients and removes waste products more efficiently than just sitting still. This can reduce stiffness and speed up recovery.

3. Get quality sleep, especially the first few hours: Your body releases the most growth hormone during deep sleep phases, which is crucial for muscle repair and recovery. Aim for 7-9 hours, and try to keep your bedroom cool and dark. Even a 20-30 minute nap within a few hours post-workout can provide recovery if you’re sleep deprived.

My Tirzepatide Update

About five weeks ago I started taking Tirzepatide. Here are a few recommendations I got at the start:

• 90-100 grams of protein

• < 40 grams total carbs (avoid starches and sugar)

• 20+ grams of fiber

• Balance fats (like avocados) to reach approximately 1500 calories per day

• No alcohol as it will stop the liver from burning fat

• 1 gram grey salt (such as Baja Gold sea salt) for electrolyte and fat metabolism

• ¾ gallons of water a day

• Sleep 8 hrs a day

• Eat small portions as digestion will slow down with gastric emptying

These are my observations at week 5

• I haven’t had quite that much daily protein

• I have effectively avoided starch and sugar

• I really enjoy avocados and salads. I’ve probably averaged less than 1500 calories daily, but had plenty of fiber

• I don’t drink alcohol and Baja Gold salt in my water is definitely an energy booster

• Constipation and general digestive discomfort is an issue and detracts from the weight loss experience

• I feel full right after eating

• My appetite is definitely lower

• My energy levels are a bit lower

• My sleep isn’t noticeably different

• My water intake is high

• I have lost 14 lbs or 2.8 lbs/week

• Conclusion: I am discontinuing Tirzepatide at this point primarily because I’ve read a handful of articles about the negative effects of GLP-1s like Tirzepatide on one’s digestive tract. My secondary rationale is that I’d like to see how I do with additional weight loss just by continuing my healthy diet and fitness routine.

FEATURE: The Power Trio for 50+: HIIT, Heavy Lifting, and Stretch

If you’re over 50 and wondering what the most effective exercise approach looks like, here’s something that might surprise you: it’s not about doing more — it’s about doing the right things with intention.

The combination of high-intensity interval training, serious weight lifting, and yoga creates a powerful trifecta that addresses the three biggest challenges we face as we age: cardiovascular decline, muscle loss, and cognitive decline.

Why This Combination Works

After 50, we lose about 1-2% of muscle mass annually if we don’t actively fight it. Weight lifting isn’t just about looking strong — it’s about maintaining the strength to carry groceries, climb stairs, and stay independent. Those heavy lifts also stimulate bone density, helping prevent the fractures that can derail our later years.

HIIT workouts maximize your time investment while delivering some of the most exciting brain health benefits we’ve seen in exercise research. Twenty minutes of high-intensity spin can deliver cardiovascular benefits that used to require an hour of steady cardio, but here’s the game-changer: the same workouts are incredibly powerful for cognitive function.

Research shows that HIIT training increases BDNF (brain-derived neurotrophic factor) — essentially fertilizer for your brain cells. It improves blood flow to the brain, supports the growth of new neural connections, and may help reduce the risk of cognitive decline. When we’re talking about maintaining sharp thinking and memory as we age, this type of training is like a direct investment in your future clarity.

Yoga brings it all together by maintaining the flexibility and balance that keep us injury-free and moving well. It’s also fantastic for stress management — and chronic stress is one of the biggest metabolic disruptors we face.

The Nutrition Connection

Here’s what many people miss: this type of training demands more from your body nutritionally. Recovery becomes paramount. Your muscles need amino acids to rebuild stronger. Your joints benefit from collagen support. Your cells require antioxidants to manage the oxidative stress from intense training. Think of proper nutrition as your training partner. Without adequate protein, omega fatty acids, and micronutrients, you’re asking your body to perform at a high level without the building blocks it needs.

Important Considerations

This approach isn’t about jumping into maximum intensity on day one. Progression matters more than perfection. If you have existing health conditions — heart issues, joint problems, or other concerns — check with your healthcare provider before ramping up intensity.

Listen to your body’s recovery signals. At 50+, we might need an extra day between intense sessions compared to our younger selves. That’s not failure — that’s wisdom.

The goal isn’t to train like a 25-year-old; it’s to train smarter for the body you have now, supporting it with nutrition you need to thrive.
