Fitness training apps?

Complete Racing Solutions

I've been using the LesMills+ app the last few months.

Do you want something that actually gives you programs and exercises to follow, or simply a fitness tracker and you do your own workouts? 
I use both Garmin connect and Strava as fitness trackers.  If anything Strava is my basic, easy reliable go-to. 
As long as I hit my hours per week and put the relative effort in the top half of the suggested range each week, then it’s working. It’s basic, but reliable.

FitBod is really good. Not only does it give you a plan, but automatically adjusts reps/weights to keep you progressing. In the beginning certain exercises may be way too easy or too hard, but do the best you can and log it accurately. You’ll have to give it a couple weeks for the algorithm to really hone in on your actual strength/fitness level, but once it does the app works really good and keeps challenging you.

Just sign up for the Troll Training. John and Alex give you programs to do every week for cardio and gym. 

Do you need much or any equipment for their plans outside of maybe just a bike and a few free weights?

You will need a form of cardio (running, cycling, rower) and a good range of weights (dumbbells and barbell work)

Another vote for Troll Training. 

Nice structure workouts with minimal equipment.

I have a spin bike, C2 rower, set of adjustable Dumbells and and pull up bar. 

Buy 3 kettlebells of different weights. 
Write 15 KB exercises on a pieces of paper and dump them in a jar. 
Draw 4 out and do the exercises, dump paper back into jar. 
Run 3-5 miles, no longer than 45 mins. 
Repeat daily.
