I received the DanceCrazy Ultra Stretch (Orange and Black), in exchange for honest review. The stretch band has loops for your arms and feet. The loops have enough room to stretch your feet or arms out.
I have used the ultra stretch for basic stretches and modified pull ups. The bands are easy to use. You slip your foot or feet into the holes and slip your arms into the front holes and stretch away.
You can purchase the Ultra stretch using the link above. The ultra stretch is prime-eligible.
