The Any-One-Can-Do-It Workout!
Warmup with mobility exercises for 5 minutes.

Perform each exercise listed below for 45 seconds going from one exercise to the next with about 5-15 seconds to transition between exercises.

Continue repeating the circuit for 30 minutes. Add in 5 minutes of your favorite core exercises then cool down with 10 minutes of mobility and stretches for the entire body. That's a 50 minute full body workout that's great for weight loss, fatloss, endurance, and strength.

Traveling squats w/ sandbag (or medicine ball) press
Rolling ropes
TRX bodyweight rows
Bosu lateral step ups w/sandbell chop
Lebert bars modified pushups
Kettlebell swings
Suicide runs

Modifications: Make this more challenging by going 50 seconds on each exercise and taking no rest between exercises (continous work circuit). Make it easier by doing 30 seconds of each exercise and eliminating all chopping motions, bosu, and/or traveling portion of squat if you (or your clients) do not have the core stability for all that. Also the one thing I would change about this workout is I would set up the lebert bars higher so a person with less upper body strength can just do incline pushups from a standing position.
