Body Pump is amazing!
I have zero coordination, so I struggled with Zumba, Step, etc. Then I tried Pump and was hooked.
As Skivvywoman says, it's group exercise to music using weights. It hits the major muscle groups, always in the same order: warm-up, squat (glutes), chest, back, triceps, biceps, lunges (legs), shoulders, abs, cool-down. Classes go for 55 minutes, and you just follow what the instructor does, adjusting your weights up and down on the barbell between tracks.
The first time I did Pump, I could barely walk the next day because my muscles hurt so much.
Now I've been going three times a week, religiously, for over 12 months and I never get sore, except for a mild full-body soreness immediately after a class, which is a feeling I actually really enjoy.
I've gone from using the lightest weights on the bar, to using 25 kg total for the squat track (12.5 on each end). I've lost inches off my hips and thighs, and have no upper-arm flab for the first time since I was a kid. And my bum has changed shape (higher and firmer). I'm not Elle Mc or anything
, but I feel amazing.
You'll either love it or hate it, but I think it's the best whole-body workout class around!
