About
ARIS PRO turns the ARIS band into a velocity-based training tool for serious lifters. Wear the band on your arm or thigh, lift, and every rep is measured: how fast the weight moved, how much power you produced, and how consistent the set was.
MEASURED ON EVERY SET
• Rep count, velocity and power, live while you lift
• Estimated 1RM and percentage of 1RM from each set
• Rep-by-rep consistency, so you can see where a set began to fade
• A five-axis set profile: technique, explosive power, hypertrophy, endurance and strength
POWER MODE
Work through a range of loads and ARIS PRO builds a power-versus-load curve for each lift, finds the load where you are most explosive, and suggests the load to try next.
TRACK YOUR PROGRESS
• Personal records for every lift, with bodyweight-relative strength levels for the common barbell lifts
• Day-by-day training history and calendar
• A seven-day muscle summary on a body map
• Your own routines, built from a library of more than 100 exercises
BUILT FOR THE GYM FLOOR
• Large numbers you can read mid-set
• Countdown beep before each set
• Light and dark themes
• English and Simplified Chinese
