Warm up first?

This is a hard session and no Dynamic Warm-up is logged in the last 45 minutes. Going maximal on cold muscles raises injury risk and gives a poorer result.

Before you start

• Clear a space about 2.5 m deep and 2 m wide. Camera at hip to chest height, full body in frame (arm-only sessions need head to hips).
• Wear fitted clothing so joints can be tracked. Good lighting, plain background if possible.
• This is a training aid, not a medical device. Effort, calories and VO2 figures are estimates from movement. A heart-rate strap makes the zones real.
• Maximal intervals are demanding. If you have a heart, joint or medical condition, or are unsure, check with your doctor or coach first. Stop if you feel unwell.
• Your camera picture never leaves this device.
