A massive 10-year study shows that muscle power, your ability to generate force quickly, is a far stronger predictor of survival than grip strength.

Men in the lowest power group had ~6x higher risk of death

Women: ~7x higher risk

Strength still matters, but speed + force seems to be a better predictor of longevity.

Think less: “How much can you lift?”
Think more: “How fast can you move it?”

Train for power. Live longer?

High-dose exercise (6x/week) combined with caloric restriction leads to superior fat loss and fully preserves muscle mass, making it an effective strategy for body composition compared to dieting with less exercise.

A recent 16-week study (PMID: 39427878) looked at how different doses of aerobic + resistance exercise combined with caloric restriction impact fat loss and muscle preservation in individuals with type 2 diabetes.

Study:

- Diet-only group – caloric restriction without exercise
- Moderate Exercise (3x/week) – 2 aerobic sessions (~50 min each) + 1 combined aerobic (30 min) & resistance (30–45 min) session
- High Exercise (6x/week) – 4 aerobic sessions + 2 combined aerobic (30 min) & resistance (30–45 min) sessions

Aerobic training – Stationary cycling, progressively increasing intensity
Resistance training – Progressive overload, 3 sets per major muscle group

Findings:

🔹 Fat Loss:

- Diet-only: 3.5% body fat loss
- Moderate (3x/week): 6.3% body fat loss
- High (6x/week): 8.0% body fat loss
🔹 Visceral Fat Reduction: Greatest in high exercise group (1,786 cm³ loss)
🔹 Muscle Preservation:
- Diet-only: -2.7% fat-free mass loss
- Moderate (3x/week): -1.9% fat-free mass loss
- High (6x/week): Fully preserved muscle mass (-0.2%)

Limitations

🔸 Short-term study (16 weeks).
🔸 Small sample size (82 participants).
🔸 Dietary adherence was self-reported.
🔸 Focused on type 2 diabetes patients and not healthy individuals (i.e., less generalizability).

A recent randomized controlled trial (PMID: 39364857) looked at the impact of a 10-week break from resistance training on long-term muscle size and strength adaptations. The study compared individuals who trained continuously for 20 weeks to those who trained for 10 weeks, took a 10-week break, and then resumed training for another 10 weeks.

The study included 42 untrained adults (55% men, 45% women) aged 18–40 years. Participants completed a standardized, supervised resistance training program consisting of two whole-body workouts per week. Strength was

Findings:

During the 10-week detraining period, the group that paused training experienced expected declines in muscle size and strength:

- Leg press 1RM decreased by 5.4%
- Biceps curl 1RM decreased by 3.6%
- Vastus lateralis cross sectional area decreased by 9.9%
- Biceps brachii cross sectional area decreased by 7.3%

However, within just 5 weeks of retraining, participants in the periodic training group fully regained lost muscle size and strength, and by the end of the study, there were no significant differences between the groups in overall muscular adaptations. The rate of muscle and strength gains was greater during the retraining period for those who took a break, demonstrating the role of muscle memory in restoring lost adaptations efficiently.

While the findings suggest that taking an extended break from resistance training does not significantly impair long-term progress in untrained individuals, they may not be fully applicable to highly trained individuals with years of resistance training experience. Well-trained individuals may experience greater losses in strength and hypertrophy during prolonged detraining due to their higher baseline levels of muscle mass and neuromuscular efficiency.

Additionally, while periodic training can facilitate rapid regains, continuous training optimizes the time spent making new gains, rather than simply recovering lost adaptations. For those seeking to maximize long-term hypertrophy and strength, maintaining at least a minimal training volume during periods of reduced training availability may be beneficial.

A Meta-Analysis (PMID: 38599681) of 20.9 million observations finds that better cardiorespiratory fitness may slash death from any kind by close to 20%

The Metabolic Equivalent of Task (“MET”) is a standardized physiological measure representing the rate of energy expenditure relative to resting metabolic rate. 1 MET = 3.5 mL O₂/kg/min, corresponding to the oxygen consumption at rest.
A recent study

The study found that every 1-MET Increase = 11-17% Reduction in All-Cause Mortality. It suggests that incremental gains in cardiorespiratory fitness confer a dose-dependent reduction in mortality risk.

In addition, A 1-MET elevation in cardiorespiratory fitness is associated with an 18% decrease in heart failure incidence and up to a 73% reduction in cardiovascular mortality.
🔹 To help put it in perspective:

- 1 MET: Resting state (sedentary behavior).
- 3 METs: Moderate-intensity activity (e.g., brisk walking).
- 6+ METs: Vigorous-intensity exercise (e.g., high-speed treadmill running).

Creatine Supplementation: Dosing Strategies

Research supports two effective approaches for creatine supplementation:

1️⃣ Loading Phase for Rapid Saturation of Creatine Stores (optional but not necessary) - Most useful when looking to maximize benefits of creatine as quickly as possible (i.e.

Does carbohydrate timing after exercise matter?

A recent study (PMID: 39263899) looked at how delaying carbohydrate intake post-exercise affects next-day performance in trained male athletes. Participants completed eight intervals at 85% peak power output, followed by a 30-minute time trial.

The athletes were divided into two groups:
1️⃣ Immediate carbohydrate Intake: Consumed 1.2 g/kg body weight of carbohydrates immediately post-exercise.
2️⃣ Delayed carbohydrate Intake: Consumed the same 1.2 g/kg body weight of carbohydrates, but three hours later.

Findings:
-The delayed carbohydrate group experienced a 30% reduction in next-day high-intensity interval performance.
-Despite similar muscle glycogen levels, they completed five fewer intervals and reported higher perceived exertion, indicating impaired recovery.

Nutrient timing may be important for endurance athletes or athletes engaged in high-intensity activities. Immediate post-exercise carbohydrate replenishment optimizes recovery and helps sustain peak performance in consecutive training sessions (at least in this case).

The total amount of protein consumed daily is the most significant factor in muscle adaptation, while protein distribution plays a secondary role. As it stands, there is insufficient evidence to recommend specific protein distribution pattern(s) to optimize muscle anabolism.

Total Daily Protein Intake Matters More Than Specific Distribution Patterns

- A meta-analysis (PMID: 28698222) of 49 studies found that ~1.6 g/kg/day of protein optimizes muscle mass and strength gains during resistance training, with no further benefit beyond this threshold.
- A more recent study (PMID: 38118410) looked at muscle protein synthesis in response to larger than average bolus (100g) of protein to ultimately conclude (as one of its conclusions) that meal timing is secondary to total intake, reinforcing the importance of meeting daily protein goals rather than focusing on rigid distribution strategies.

There is Limited Evidence Supporting the Need for an "Optimal" Distribution: A review (PMID: 32429355) on protein distribution and muscle-related outcomes concluded that current evidence is inconsistent regarding whether a specific protein distribution pattern enhances muscle health beyond total intake. While an "optimal" distribution pattern theoretically reduces amino acid oxidation and improves efficiency, the primary determinant of muscle adaptation remains total protein intake rather than precise meal timing.

✅ Prioritize total protein intake (1.5-2.0 g/kg/day) to maximize muscle growth and recovery.
✅ Rigid meal timing strategies are not necessary, but ensuring ≥20g of protein per meal may help maintain a consistent anabolic response throughout the day for young healthy individuals.
