In my opinion, bodyweight exercises are some the best exercises in the world. If you can do a lot of any of these exercises, maybe you can do 100 press ups in a row, then just add some resistance to them until you can only manage 20 on so on and so forht. You can always increase the resistance as in weight lifting with these exercises. There seems to be a big emphasis in gymwork and i think that going back to basics could provide better results. Note-these exercises are for strength and muscle endurance not size. #5. Pull ups - same as chin ups but with an overhand grip. #4. Chin ups - think we all know what these are. #3. Press ups - regular/diamond/wide and elevated. #2. Seated tricep dips - add a weight disc to your lap to increase intensity #1. Parallel bar dips - lean forwards for more of an emphasis on the chest or keep straight for more on the triceps. I am confident that performing these will increase your strength.
