Started a new program today. Uses only a barbell and everything else is body weight exercises. Had to cheat and use the smith machine for squats as im not confident with squatting atm as I have very weak legs/glutes.
Squat 5x5 (45kg)
Bench Press 5x5 (40kg)
Inverted Rows 6,6,5 (3 sets x until failure)
Push-ups 10,8,6 (3 sets x until failure)
Reverse Crunch 3x12
Start really slow with the squats but I really wouldn't recommend a smith machine. Just do it in a squat rack.
Check out the programs "Starting Strength"... I'm still using a variation of it and I have been lifting for close to two years
When I first started I only could really put 35 on each side... lol.
