1. Tree pose and curl
Holding both weights in left hand, press left foot into floor and slowly raise right knee to place sole of right foot against left inner thigh or calf. Grab 1 weight with right hand. Holding pose, do 10 bicep curls. Switch feet. Repeat.
Perfect your form: Avoid placing foot on knee. Engage core to stay balanced.
Dial it down: Ditch the hand weights.
Amp it up: Increase reps and try placing foot higher.
