Exercises: elbow, footwork, etc

Having had a little time off regular fencing due to holidays and so on, and also because of developing some elbow soreness, I've collected some information on things to practice, including basic footwork and extension stuff, elbow stretches and so on.

I asked about elbow soreness on the Reddit fencing subreddit:

Suggestions include:

• "ice it after every practice"
• rest, dont overdo it in practice
• beware of hyper-extending your arm
• practice keeping actions small and relaxed, with fewer binds, using a "giving motion" ("here, let me share this with you...") instead of hyper-extending
• maybe try a tennis elbow strap

Also these "therabar" rubber bar exercises:

There are other therabar exercises but I haven't gotten to them yet.

On practicing footwork and extension basics, these videos are good:










And here is a long video with many exercises. Specific exercises begin at 14:20 and get increasing difficult, far beyond what my old body can hope to do.
