About this app
"I'm working hard but not gaining muscle." The reason might be a lack of total volume management. Souhuka calculates and tracks your total training volume (weight × reps × sets) in real time — the most important metric for muscle hypertrophy. [Real-Time Volume Calculation] Just enter weight, reps, and sets — your total volume is calculated instantly. Log your workout in 1 second, even mid-session. [Automatic Week-over-Week & Session Comparison] See exactly how many kg more you lifted vs last week, and what % you've grown since your last session. Visible progress keeps you motivated. [Progress Charts by Muscle Group] Track volume trends for chest, back, legs, shoulders and more with easy-to-read charts. [Full Training History] Review all past records and train with your previous self as your benchmark. [Share to Instagram Stories] Share your daily training results to Instagram Stories with one tap. Show your progress to friends and boost your motivation even further. Perfect for: · Anyone aiming for muscle hypertrophy or bulking up · Those who want to log every workout · People who prefer data-driven training over guesswork Feel your muscle growth through the numbers.
