Doing regular strength or cardio workouts for 16 weeks can make your skin tighter and healthier-looking by improving the support structure underneath it.

Assessment Explanation
The claim specifies a controlled intervention (16 weeks of training) with measurable biological outcomes (skin elasticity, LEP), which are commonly assessed in clinical exercise studies. Randomized controlled trials (RCTs) with objective skin measurements (e.g., cutometer, ultrasound elastography) can establish causality. The use of 'improve' and 'reduce' is appropriate if the study design controlled for confounders and showed statistically significant changes. No overstatement is present as long as the results were statistically significant and clinically relevant.
More Accurate Statement
“A 16-week program of either resistance training or aerobic training significantly improves skin elasticity and reduces upper dermal echogenicity (LEP) in middle-aged Japanese women, suggesting enhanced dermal extracellular matrix integrity.”

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
Evidence from Studies
Supporting (1)
Resistance training rejuvenates aging skin by reducing circulating inflammatory factors and enhancing dermal extracellular matrices
The study found that both lifting weights and cardio exercises for 16 weeks made skin more elastic and healthier in middle-aged Japanese women, just like the claim says.
