This is one of the most impressive athletic performances I’ve seen:

This is the Firecracker jump rope team made up of 4th through 8th grade students.

Great explanation on how to position yourself for a deadlift here:

If you don’t already know the exercise well, this alone is not nearly enough to start pulling real weight off the floor safely. I’m not going to try to teach the deadlift (especially online) but there are plenty of videos if you want to [...]

Interesting article here with some exercises for ankle stability. This is an issue for me (martial arts stress my ankles) and the article gave me a couple of additional ideas:
Tree pose (yoga) – a bit harder than simply standing on one foot.
Juggle on one foot – probably a bit more advanced than catching a ball [...]

Here’s an article that talks about some exercises for strengthening the core. These are done in addition to ab isolation exercises like crunches and in addition to glute activation work and are said to improve core strength, posture, and physique:

For a few weeks you can spike testosterone and HGH with shorter (1 minute) rests between sets. However the difference declines by 5 weeks into a routine. Over 10 [...]

Pretty tough finding information on Vin Diesel’s workouts. Ive gathered online that he likes free weights, compound movements, yoga, and pilates.
I also found that he has trained in MMA, specifically Kali.
Q: What is your Riddick workout?
VIN: The Riddick workout started before I went up there. I was training with a UFC guy, Ultimate Fighting Championship [...]

Nice site here on hand health. You may want something simple like a stronger grip but training grip only leads to imbalanced hands and raises the potential for injury so like it or not, you have to train the hands in all kinds of different ways.

Interesting article here on the importance of glute strength and there are several tests you can do to find which stretches / exercises you need to balance your glutes / hip flexors / etc.

Interesting article here that makes a strong case for doing 1 leg squats because these involve more muscles and are more functional than traditional squats.
Also mentions 1 leg straight leg deadlifts and slideboard leg curls (which seem to require some fancy equipment I’ve never seen before).
