Whats the best piece of gym equipment or fitness device?

For a runners, hurdlers, LJ, TJ and HJ:

Dip bars

3 exercises to do

Dips - delts, triceps, chest

Inverted Rows (lying back, hand on each bar, pull yourself up) - back, delts

Leg lifts. (Starting position for dip, but instead of dipping pull legs up and forward) - core, hip flexors

I'm gonna say one of the best pieces of cross training equipment for a runner is the elliptical machine. Great machine to add to your training for those of us who are more frail with the mileage, plus a great way to maintain basic aerobic fitness when an injury keeps you away from the high impact of running

Nice addition - a great, under-used piece of equipment.

At home, it's the foam roller for me.

Squat rack.

OHP, DL, squat.

The old Stairmaster was great. I never had an injury that I couldn't just continue to train on the Stairmaster with.

Agree. It's hard to get the interval sessions in during the winter up north and the ERG allows me to get some quality VO2max reps in.

Also, it is about a 1:1 ratio compared to running, calorie and effort wise.

I have bosu thing that is useful and similar.

I do a lot of motocross, bike stuff like cyclocross & road crits with a bit of mountain biking as well, and as much downhill skiing as possible. All of those balance things are helpful.

You can do everything you could want to do in a squat rack with a barbell:

Squat, OHP, Rows, RDLs, curls, tricep extentions, pull ups (in most modern racks anyway), and bench press.

No machines necessary.

No love for the cross trainer ?

Never knew they made this, but they upped their game with the thigh master vibrato. Trying to rival the shake weight.

Pull up bar+ push ups + running will get you a long way.

Apparently, the SJU track team feels the same way

Lower body: Barbell and squat rack.

Upper body: Gymnastic rings.

Smith Machines are underrated. They are very versatile and effective.

Has anyone said a treadmill yet? It’s straight up -6 outside right now

If the hex bar was so great you would see more of them. I never see any. The Olympic barbell ranks supreme. Bench, incline bench, deadlift, lunges clean and jerks, the list goes on and on.
