Plan around your goals, schedule, and available equipment, then make adjustments as real life happens. MAKE YOUR WEEK YOURS Create a weekly plan with your preferred training method, available days, and equipment. Review the exercises and targets before scheduling. Reuse a successful week, move sessions on the calendar, and use simple check-ins to help shape what comes next. LOG THE WAY YOU TRAIN Record weights, reps, timed exercises, and cardio distance. Add or remove sets, swap exercises, and adjust the order during your workout. Switch between pounds and kilograms for individual exercises, see your last performance, and use rest and exercise timers without losing your place. BUILD ON YOUR PROGRESS Get reviewable next-time suggestions based on completed workouts and your feedback. Keep control of every target: suggestions are a starting point, and you can adjust them to match your equipment and how you feel.

Equipment-aware workouts help you adapt your session to the gym or kit you have available.
