Hi Kelly,
I see you haven't gotten an answer yet, so I will do my best here, but I am not great with explaining things.
Walking lunges: just like doing alternating front lunges, except you bring your back leg forward, taking a step and going into a lunge with that leg. You are literally lunging as you walk. You still need to keep the movement vertical, not leaning forward or backward, and your back knee shouldn't touch the floor. Also still need to keep a 90 degree angle at the knee bend.
Toe Touches: Standing, feet about hip width apart, you bend from the hips downward and touch your toes. Keep your knees a bit soft. Stand back up, touching your waist or hips, then raise your arms over your head, then back to waist and bend again. And so on. It would be a four count move: Hands up, waist, toes, waist.
Burpees: known as squat thrusts because you go into a deep squat, place hands on the floor, thrust your legs out behind you, bring them back with knees bent toward your chest, then stand/jump up. If you have Boot Camp, these are done as "mountain climbers, because you thrust both legs out, then bring them in toward the chest one at a time (as if climbing), before jumping back up. Cathe answered something about these somewhere; you may try searching.
As for Pure Strength, you may try searching for this, too, if you haven't already. I am not sure of her weights, but I will try to figure it out over the next couple days as I am doing those workouts Thurs & Fri.!!
HTH, Julie
