Wall balls - take a 20 pound medicine ball, do a full squat, throw it up to 10 feet, catch it and full squat again. Anything around 100 reps works awesome
Kettlebell swings - These incenerate everything, from your legs, back and shoulders. Go all the way to above your head, ears through the window
Deadlifts - proper form deadlifts, chest up and drive your heels into the ground, bar starts against your shins
** Front Squats - probably one of my favorites, you use about 70% of what you back squat because it's a killer workout. Load the bar into the "rack position", squat all the way down till your knees are below parallel
Overhead squat - this is a core, leg and shoulder killer. Start with just the bar, engage your shoulders, and squat down below parralel. This works your ENTIRE core to balance. Don't go heavy on these, starting with the 45 pound bar is more than enough
Olympic lifts (snatch, jerk/split jerk, clean, squat snatch) - these work awesome, but you'll need to find an instructor to get your form right. They are technical moves and need proper training
Here is Donny Shankle doing some of these "olympic lifts"
that guy is wicked strong
I would be careful, most of these could also really hurt your back, especially if you have never done them before or dont know how much weight to use. This exercise really helps my back and poses no risk to hurt you.
at $1050 there is no way this is going to go well, especially under the name JT. Too much competition at that price point. Maybe in the $500 range it would work but not $1050 when you can buy a brand new ego 11 for under that.
