You don’t need to train every day—just twice a week for two months can make your upper and middle thighs bigger, as long as you do enough total work.
Scientific Claim
Resistance-trained males can achieve significant muscle hypertrophy in the proximal and middle lateral thigh with as little as two resistance training sessions per week over 8 weeks, provided total volume is sufficient.
Original Statement
“A significant main effect of time was revealed for MT at the proximal (P = 0.0001) and middle (P = 0.0001) aspects of the lateral thigh for all training groups.”

Assessment Explanation
The time effect is strong and consistent. Probability language is warranted due to small sample size and lack of volume quantification details.
More Accurate Statement
“Resistance-trained males can likely achieve significant muscle hypertrophy in the proximal and middle lateral thigh with as little as two resistance training sessions per week over 8 weeks, provided total volume is sufficient.”
Evidence from Studies
Supporting (1)
Rest-pause and drop-set training elicit similar strength and hypertrophy adaptations compared to traditional sets in resistance-trained males.
Even just working out twice a week for 8 weeks made the upper and middle parts of the thighs bigger, as long as the total amount of work was enough—so yes, you don’t need to train every day to build muscle.
