No offense to the guys that do "isolation" movements, but by performing single joint movements, it makes your body more prone to injuries. You might be making certain parts of your body stronger but not overall. Stick with movements that creates a kinetic chain, movements that make the whole body work rather than an isolated area. For example, take the leg extensions... It's a single joint movement that works mainly the quads and can cause knee joint problems.. where exercises like squats, deadlifts, overhead squats are multi joint movements working your entire body to move the weight, therefore burning more calories, creating strength in the entire body as well as making stable and strong joints.
Exercises should consist of
deadlifts
cleans
snatch
squats - front, overhead, back
body weight exercises - handstand pushups, pushups, dips, pull-ups
