Lay on mat with knees bent and feet on ground with arms beside you. Then sit up, bending one leg under you and put other foot on ground, using the strength of that leg lift yourself up – try to not use hands for support, and get up to standing. Then reverse movement to lie down again and continue repeating these movements. To modify, use your hands for support to help you get up.

Start in high plank position and jump both legs together at once to one side, just below one hand, and then back, next jump both legs to opposite side close to same side hand and back, 3^rd point jump is same as a ½ burpee, jumping both feet forward and then back.

From standing, jump legs out and squat down simultaneously touching ground with fingers while in squat, then jump feet back in and stand up. 

From standing position, bend knees into squat and reach down touching fingers to sides of feet. Then with an explosive jump, come up into a jumping jack, jumping legs out wide while and bringing arms out at sides and above head, then jump feet back in close together, coming down into squat and touching sides of feet again. This is one rep. Continue repeating movements doing as many reps as indicted or as many reps as you can for time.

Standing with feet hip width apart, squat down and place hands on ground in front of you, jump legs back into plank position, do a push up, jump legs back in and jump up in the air.

Get into crab position and then bring your hips down closer to ground putting weight more on tricep muscles of arms and lift one leg up keeping it straight with foot towards ceiling; this is your start position. Bring down the raised leg and right away lift the opposite leg that was on ground. When the raised leg comes down your hips naturally raise up and when your other leg goes up your hips go down, at this point when they go down do a tricep dip with your arms, focusing on and using your tricep muscles. Each time leg is raised is one rep.
