I'm still careful not to leap too high or to leap repeatedly, but that's the only limitation I'm experiencing from my Achilles tendon injury nearly five years ago.
I wanted to start dancing again as I hadn't been exercising as regularly as I used to, and had been experiencing a certain muscle weakness in my legs and a sense of weakness in my knees. It certainly helped, although weekly rather than fortnightly would be preferable for me. We're taking a break for winter, and resuming in March.

However, it's now falling apart after having been rewelded about three times, so whilst I look for a replacement I'm aiming to do more walking each day.
If you're considering the conservative treatment route, i.e. not undergoing an operation after an Achilles tendon injury, I hope that reading about my experiences helps you come to a decision.
