I think it's the right choice. The gym needs a "two month notice" for cancellation. I can still go until late June, though.
$43/month isn't work that gym. There is one, old, noisy squat rack, surrounded by two smith machines (the smith machines are very intimidating

), and there is always some Curl Hero using it, with his headphones and Red Bull, taking 10 minutes between each of his 10 sets. There is also a guy who uses the squat rack to STRETCH. he doesn't even squat the bar. He spends 15+ minutes putting his legs and arms on the bar, etc, just to stretch.
Anyways, yesterday I did Interval Running:
Was planning to do:
4 x 800 meters
4 x 50 meters
After the second set on 800, I started to cramp in both calves (calf cramps are a huge problem with me, sometimes after doing a serve my calf(ves) go into a full on, unbelievably painful cramp(s)). When I get a full cramp it puts me out for 2+ weeks. Thank goodness they didn't cramp, but it was very close.
Stopped after second set, couldn't run anymore. Could barely walk. Went home and did core, which included:
Flag x 5
Side bends x 6 per side x 50 lbs
Supermans x 15
Medicine ball twist throws x 8 per side
Did this circuit total of 3 times, and finished with plank hold for as long as I could.

Calves feel very sore today, but will still proceed with strength workout.
I've tried a lot of things for the cramps (potassium pills, tons of bananas, etc). The best thing that has helped was using a tennis ball and massage stick. This really loosened them up. The only problem was that it would take so long to loosen them up.
After the strength workout today (which includes one legged squats and glute hamstring raise), I'm going to add a set or two of calf raises. Maybe the cramps are due to muscle imbalance. My quads are rock solid, but my calves are very squishy, even when flexed.
I'll post again after I see how everything goes.
