The world’s most advanced barbell performance training tool. FLEX measures lift performance and gives powerful real-time feedback through your iPhone, iPad or Android device.
VBT is as effective for training for power, strength, hypertrophy or speed and has been used in the weights rooms of pro and olympic athletes for decades.
Using FLEX to measure velocity also gives you immediate feedback while you lift, which can narrow your focus and amplify your performance.
Any training decision can be managed objectively with velocity - set training zones, dictate session intensity, prescribe fatigue limits and program short and long term cycles. Anything you can do with percentage based programming you can do with more precision once you have access to objective measures.
Track and store every single rep. A comprehensive training log is automatically stored and can be reviewed at any time. Drill down and analyse power, velocity, range of motion and even review technique with bar path tracking. Pull back for an overviews of your training over time. FLEX even sends you monthly progress reports, so you can view trends and see if you’re improving on a monthly basis.
