Strong tracks your sets and reps. tr8ck tracks what determines whether those sets are strong or weak — sleep quality, nutrition timing, GLP-1 medication, mood, and recovery. Both together is the complete picture.

Strong is one of the best gym logging apps ever made. Here's what it does that tr8ck genuinely can't match in the weight room.
Strong has spent years perfecting the gym logging experience. These are its genuine advantages:
tr8ck tracks the 23 hours outside the gym that determine how strong you'll be inside it:
Progressive overload requires more than adding weight. It requires the recovery, nutrition, sleep, and hormonal environment to support it.
GLP-1 medications like Ozempic are known to affect muscle mass preservation during weight loss. Many users notice changes in gym performance, energy levels, and recovery on injection days. Strong records the session output — tr8ck tracks the GLP-1 dose, timing, and correlates it with your energy, sleep, and gym performance over weeks. That's the insight loop that actually helps you optimize.
Gym specificity vs. whole-health context — both matter for serious lifters
