Tim Cochran is the founder of RESISTX, an offline-first iOS and Android app that keeps a lifter’s training, food, body composition, bloodwork, sleep and protocols in one place. He is based in Sydney.
Tim is not a coach, and RESISTX isn’t one either. He has spent years training under good coaches, and years building education businesses for coaches, and that is where the design comes from: collect everything, watch the trend, change one thing at a time. RESISTX is the instrument that makes that possible for lifters coaching themselves. It does the collecting; the judgment stays with the lifter.
Every article on this site is drafted with AI assistance and checked by Tim before it is published: the numbers, the sources, and every claim about another app.
What is adaptive TDEE? How intake and weight trends estimate maintenance calories, why the number changes, and what incomplete logs or water can distort.
Hevy vs Strong is a small question: both log sets and an effort field. Neither lets you configure and score weekly sets per muscle against your own volume landmarks. What that costs.
MEV MAV MRV explained in practice: how to find your own volume landmarks, structure a 5-week mesocycle around them and track them as they shift over time.
RPE vs RIR: both measure effort but they do different jobs. Prescribe intensity with RIR, autoregulate with RPE, and log both so the gap becomes a signal.
Most apps count total sets, not sets per muscle group per week. How to count compounds with the 1.0 / 0.5 rule and check totals against your landmarks.
