Building muscle after 40: The science of getting stronger when recovery slows down
Dr. Bruno Rodriguez, DPT, CSCS: Strength, Recovery, and Physical Therapy Expert
Jan 26, 2026 · 10 min read
Men over 40 can still build muscle and strength, but anabolic resistance and slower tissue repair often extend recovery from heavy sessions to roughly 48–72 hours, meaning the hypertrophy stimulus has to be higher to meaningfully trigger muscle protein synthesis. Here’s how to adjust training volume and target 30–40 g of high‑quality protein (~3–4 g ...
Bulking vs cutting: The science of body recomposition for men
Dr. Bruno Rodriguez, DPT, CSCS: Strength, Recovery, and Physical Therapy Expert
Jan 26, 2026 · 11 min read
Bulking and cutting work by deliberately shifting energy balance: a 250–500 calorie daily surplus supports muscle protein synthesis and hypertrophy, while a sustained calorie deficit drives fat oxidation but can increase muscle protein breakdown. The key to body recomposition is committing to one clear signal for 12–16 weeks—rather than chasing muscle gain and leanness at ...
What muscles does cycling work? A physiologist’s guide to building power
Dr. Bruno Rodriguez, DPT, CSCS: Strength, Recovery, and Physical Therapy Expert
Jan 18, 2026 · 10 min read
Cycling primarily works the quadriceps, gluteus maximus, and hamstrings, while the core and hip–lower back stabilizers brace the pelvis to transfer force through a closed-kinetic-chain pedal stroke. If you only push down on the pedals you can leave “half your potential power” unused and increase knee load—here’s how biomechanics and bike fit help you recruit ...
Weights or cardio first? The evidence-based order that gets men results faster
Dr. Bruno Rodriguez, DPT, CSCS: Strength, Recovery, and Physical Therapy Expert
Jan 17, 2026 · 11 min read
For most men trying to build strength and muscle, do weights first and finish with cardio, because cardio-first increases fatigue and AMPK signaling (and can drain glycogen), which can reduce lifting volume and potentially blunt mTOR-driven hypertrophy. If endurance is your main goal or you’re splitting sessions across the week, the “best” order changes—here’s how ...
How long does it take to lose muscle? The science of detraining
Dr. Bruno Rodriguez, DPT, CSCS: Strength, Recovery, and Physical Therapy Expert
Jan 17, 2026 · 11 min read
Measurable muscle atrophy typically doesn’t begin until about 2–3 weeks of complete inactivity, with the first 5–7 days off usually reflecting depleted glycogen and water rather than lost contractile tissue. The real risk window—and why immobilization (bed rest or a cast) changes the timeline—comes down to how quickly protein synthesis drops when mechanical tension disappears. ...
