Do these 3-4 times a week to see results

1. Plank with a twist(Targets abs and obliques):

1. Begin on ground in plank position, balancing on forearms and toes, body forming a straight line from head to heels. 
2. Keeping shoulders and feet still, rotate hips to the ground. Twist to the right making your right hip touch the ground, then go to center. Do the same with left hip. That’s one rep; do 10-20

2. Dip and hip raise(Targets triceps and butt):

1. Sit on ground with knees bent 90 degrees, feet flexed so heels are on ground, and place palms flat on either side of hips, fingers forward.
2. Lift hips about 4 inches of the ground, then bend elbows behind you and lower hips toward ground.
3. Straighten arms and press hips up to form table top. 
4. Return to start. Do this 10-15 times.
