CONSOLIDATED WORKOUT KNOWLEDGE (PART 1)
(A quick summary of fundamental knowledge and common questions, only FACTS)
1. WHY WEIGHT TRAINING:
Boosts the health of vital parts: heart, respiratory system, among others. It also helps build muscle, increase bone density (often overlooked but challenging to improve as you age), and perfect/adjust posture.
It's never too early or too late to start weight training.
2. PROTEIN AND EXERCISE:
How much is enough:
+) Sedentary individuals: 0.8g/kg body weight
+) Those weight training, aiming to build muscle: 1.6-2.2g/kg body weight (This applies to normal individuals; for overweight individuals, it should be calculated based on the target weight)
There is no clear evidence that a healthy person experiences kidney issues with a protein intake greater than the above amount.
3. INTERMITTENT FASTING & MUSCLE SYNTHESIS:
If following basic cycles of IF: 16/8, 18/6, 20/4, it does not significantly impact muscle growth. Nutrients can be stored for 24 hours or more, so these fasting methods do not greatly affect the body's adaptation process.
Compensating between days will also help you grow muscles well. Missing one day a week doesn't have much impact on adaptation (remember to compensate enough).
4. HOW LONG AFTER EXERCISE TO EAT:
The sooner, the better (when heart rate, breathing rate are stable, and sweating has reduced). If you can't eat immediately, there's no problem, as explained above.
5. SHOULD YOU DO MANY REPS OR FEW REPS?
Within the range of 3-40 reps with the same volume, effort level, muscle development is similar.
Low reps (heavy weights) promote strength development better than high reps.
Reps above 15 have effects on both cardio and muscle growth.
6. DOING 100% CARDIO TO LOSE FAT:
Efforts in doing cardio do not burn as much energy as USING EFFORT to refrain from eating.
Cardio often results in both fat and muscle loss simultaneously (70% fat loss: 30% muscle loss).
For obese individuals, they may only lose fat because they have too much fat.
Cardio is necessary for cardiovascular health, but it's not the key to fat loss.
Cardio helps improve heart and lung health, making weight training less tiring, leading to better muscle growth.
